Image analysis software - Image processing and display ---------------------------------------------------------- [ MAJOR reorganization + additions! ] [ Here I include a half baked list from ritley@uimrl7.mrl.uiuc.edu (Kenneth Ritley) on such softare, plus additions from Stephen L. Pendergast's <penderga@HAC2ARPA.HAC.COM> list, which was derived in turn from Tim Allen's <tim.allen@dartmouth.edu> list -- phew!! and various other sources here and there. Also I tried to make a major reorganization under the various platform categories . Still don't know how to separate the Remote Sensing stuff Any ideas?? -- nfotis ] PC and Mac-based tools (multi-platform software) ====================== IMDISP ------ IMDISP Written at JPL and other NASA sites. Can do simple display, enhancing, smoothing and so on. Works with the FITS and VICAR/PDS data formats of NASA. Can read TIFF images, if you know their dimensions [PC and Macs] LabVIEW 2 --------- LabVIEW is used as a framework for image processing tools. It provides a graphical programming environment using block diagram sketch is the "program" with graphical elements representing the programming elements. Hundreds of functions are already available and are connected using a wiring tool to create the block diagram (program). Functions that the block diagrams represent include digital signal processing and filtering, numerical analysis, statistics, etc. The tool allows any Virtual Instrument (VI, a software file that looks and acts like a real laboratory instrument) to be used as a part of any other virtual instrument. National Instruments markets plug-in digital signal processing (DSP) boards for Macintoshs and PC compatables that allow real-time acquisition and analysis at a personal computer. New software tools for DSP are allowing engineers to harness the power of this technology. The tools range from low-level debugging software to high-level block diagram development software. There are three levels of DSP programming associated with the NB-DSP2300 board and LabVIEW: Use of the NB-DSP2300 Analysis Library: FFTs, power spectra, filters routines callable from THINK C and Macintosh Programers Workshop (MPW) C that execute on the NB-DSP2300 board. There is an analysis Virtual Interface Library of ready-to-use VIs optimized for the NB-DSP2300. Use of the National Instruments Developers Toolkit that includes an optimizing C compiler, an assembler and a linker for low-level programming of the DSP hardware. This approach offers the highest level of performance but is the must difficult in terms of ease of use. Use of the National Instruments Interface Kit software package which has utility functions for memory management data communications and downloading code to the NB-DSP2300 board. (This is the easiest route for the development of custom code.) Ultimage Concept VI ------------------- Concept VI by Graftek-France is a family of image processing Virtual Instruments (VIs) that give LabVIEW 2 (described above) users high-end tools for designing, integrating and monitoring imaging control systems. A VI is a software file that looks and acts like a real laboratory instrument. Typical applications for Concept VI include thermography, surveillance, machine vision, production testing, biomedical imaging, electronic microscopy and remote sensing. Ultimage Concept VI addresses applications which require further qualitative and quantitative analysis. It includes a complete set of functions for image enhancement, histogram equalization, spatial and frequency filtering, isolation of features, thresholding, mathematical morphology analysis, density measurement, object counting, sizing and characterization. The program loads images with a minimum resolution of 64 by 64, a pixel depth of 8, 16, or 32 bits, and one image plane. Standard input and output formats include PICT, TIFF, SATIE, and AIPD. Other formats can be imported. Image enhancement features include lookup table transformations, spatial linear and non-linear filters, frequency filtering, arithmetic and logic operations, and geometric transformations, among others. Morphological transformations include erosion, dilation, opening, closing, hole removal, object separation, and extraction of skeletons, among others. Quantitative analysis provides for objects' detection, measurement, and morphological distribution. Measures include area, perimeter, center of gravity, moment of inertia, orientation, length of relevant chords, and shape factors and equivalence. Measures are saved in ASCII format. The program also provides for macro scripting and integration of custom modules. A 3-D view command plots a perspective data graph where image intensity is depicted as mountains or valleys in the plot. The histogram tool can be plotted with either a linear or logarithmic scale. The twenty-eight arithmetic and logical operations provide for: masking and averaging sections of images, noise removal, making comparisons, etc. There are 13 spatial filters that alter pixel intensities based on local intensity. These include high-pass filters for contrast and outlines. The frequency data resulting from FFT analysis can be displayed as either the (real , imaginary ) components or the (phase, magnitude) data. The morphological transformations are useful for data sharpening and defining objects or for removing artifacts. The transformations include: thresholding, eroding, dilating and even hole filling. The program's quantitative analysis measurements include: area, perimeter, center of mass, object counts, and angle between points. GTFS, Inc. 2455 Bennett Valley Road #100C Santa Rosa, CA 95494 707-579-1733 IPLab Spectrum -------------- IPLAB Spectrum supports image processing and analysis but lacks the morphology and quantitative analysis features provided by Graftek-FranceUs Ultimage Concept VI. Using scripting tools, the user tells the system the operations to be performed. The problem is that far too many basic operations require manual intervention. The tool supports: FFTs, 16 arithmetic operations for pixel alteration, and a movie command for cycling through windows. Macintosh-based tools ===================== NCSA Image, NCSA PalEdit and more --------------------------------- NCSA provides a whole suite of public-domain visualization tools for the Macintosh, primarily aimed at researchers wanting to visualize results from numerical modelling calculations. These applications, documentation, and source code are available for anonymous ftp from ftp.ncsa.uiuc.edu. Commercial versions of the NCSA programs have been developed by Spyglass. Spyglass, Inc. 701 Devonshire Drive Champaign, IL 61820 (217) 355-6000 fax: 217 355 8925 NIH IMAGE --------- Available at alw.nih.gov (128.231.128.7) or (preferably) zippy.nimh.nih.gov [128.231.98.32], directory:/pub/image. It has painting and image manipulation tools, a macro language, tools for measuring areas, distances and angles, and for counting things. Using a frame grabber card, it can record sequences of images to be played back as a movie. It can invoke user-defined convolution matrix filters, such as Gaussian. It can import raw data in tab-delimited ASCII, or as 1 or 2-byte quantities. It also does histograms and even 3-D plots. It is limited to 8-bits/pixel, though the 8 bits map into a color lookup table. It runs on any Mac that has a 256-color screen and a FPU (or get the NonFPU version from zippy.nimh.nih.gov) PhotoMac -------- Data Translation, Inc. 100 Locke Dr. Marlboro, MA 01752 508-481-3700 PhotoPress ---------- Blue Solutions 3039 Marigold Place Thousand Oaks, CA 91360 805-492-9973 PixelTools and TCL-Image ------------------------ "Complete family of PixelTools (hardware accelerator and applications software) for scientific image processing and analysis. Video-rate capture, display, processing, and analysis of high-resolution monochromatic and color images. Includes C source code." TCL-Image: "Software package for scientific, quantitative image processing and analysis. It provides a complete language for the capture, enhancement, and extraction of quantitative information from gray-scale images. TCL_Image has over 200 functions for image processing, and contains the other elements needed in a full programming language for algorithm development -- variables and control structures. It is easily extensible through "script" (or indirect command) files. These script files are simply text files that contain TCL-Image commands. They are executed as normal commands and include the ability to pass parameters. The direct capture of video images is supported via popular frame grabber boards. TCL-Image comes with the I-View utility that provides conversion between common image file types, such as PICT2 and TIFF." Perceptics 725 Pellissippi Parkway Knoxville, TN 37933 615-966-9200 Satellite Image Workshop ------------------------ It comes with a number of satellite pictures (raw data) and does all sorts of image enhancing on it. You'll need at least a Mac II with co- processor; a 256 color display and a large harddisk. The program doesn't run under system 7.x.ATE1 V1 In the documentation the contact address is given as: Liz Smith, Jet Propulsion Laboratory, MS 300-323, 4800 Oak Grove Dr,.Pasadena, CA 91109 (818) 354-6980 Visualization Workbench ----------------------- "An electronic imaging software system that performs interactive image analysis and scientific 2D and 3D plotting." Paragon Imagine 171 Lincoln St. Lowell, MA 01852 508-441-2112 Adobe Photoshop --------------- The tool supports Rtrue colorS with 24-bit images or 256 levels of grey scale. Once an image has been imported it can be Rre-touchedS with various editing tools typical of those used in Macintosh-based RpaintS applications. These include an eraser, pencil, brush and air brush. Advanced RpasteS tools that control the interaction between a pasted selection and the receiving site have also been incorporated. For example, all red pixels in a selection can easily be preventing from being pasted. Photoshop has transparencies ranging from 0 to 100%, allowing you to create ghost overlays. RPhoto-editingS tools include control of the brightness and contrast, color balancing, hue/saturation modification and spectrum equalization. Images can be subjected to various signal processing algorithms to smooth or sharpen the image, blur edges, or locate edges. Image scaling is also supported. For storage savings, the images can be compressed using standard algorithms, including externally supplied compression such as JPEG, availlable from Storm Technologies. The latest version of Adobe Photoshop supports the import of numerous image formats including: EPSF, EPSF, TIFF, PICT resource, Amiga IFF/ILBM, CompuServe GIF, MacPaint, PIXAR, PixelPaint, Scitex CT, TGA and ThunderScan.. Adobe Systems, Inc. 1585 Charlestown Road PO Box 7900 Mountain View, CA 94039-7900 415-961-4400 ColorStudio and ImageStudio --------------------------- ColorStudio is an image-editing and paint package from Letraset that has more features than Adobe Photoshop but is decidedly more complex and therefore more difficult to use. Several steps are often required to accomplish that which can be done in a single step using Photoshop. The application requires a great deal of available disk space as one can easily end up with images in the 30 MB range. The program provides a variety of powerful selection tools including the "auto selection tool" which lets the user choose image areas on the basis of color, close hues, color range and mask. ImageStudio: Don't know... Letraset USA 40 Eisenhower Drive Paramus, NJ 07653 201-845-6100 Dapple Systems -------------- "High resolution image analysis software provides processing tools to work with multiple images, enhance and edit, and measure a variety of global or feature parameters, and interpret the data." Dapple Systems, 355 W. Olive Ave, #100 Sunnyvale, CA 94086 408-733-3283 Digital Darkroom ---------------- The latest release of Digital Darkroom has five new selection and editing tools for enhancing images. One such feature allows the user to select part of an image simply by "painting" it. A new polyline selection tool creates a selection tool for single pixel wide selections. A brush lets the operator "paint" with a selected portion of the image. Note that this is not a true color image enhancement tool. This tool should be used when the user intends to operate in grey-scale images only. It should be noted that Digital Darkroom is not as powerful as either Adobe Photoshop or ColorStudio. Silicon Beach Software 9770 Carroll Ctr. Rd., Suite J San Diego, CA 92126 619-695-6956 Dimple ------ It is compatible with system 6.05 and system 7.0 , requires Mac LC or II series with 256 colours, with a recommended min of 6Mb of ram. It has the capability of reading Erdas files. Functions include; image enhancement, 3D and contour plots, image statistics, supervised and unsupervised classification, PCA and other image transformations. There is also a means (Image Operation Language or IOL) by which you can write your own transformations. There is no image rectification, however Dimple is compatable with MAPII. The latest version is 1.4 and it is in the beta stage of testing. Dimple was initially developed as a teaching tool and it is very good for this purpose." "Dimple runs on a colour Macintosh. It is a product still in its development phase.. i.e. it doesn't have all the inbuilt features of other packages, but is coming along nicely. It has its own inbuilt language for writing "programs" for processing an image, defining convolution filters etc. Dimple is a full mac application with pull down menus etc... It is unprotected software." Process Software Solutions, PO Box 2110, Wollongong, New South Wales, Australia. 2500. Phone 61 42 261757 Fax 61 42 264190. Enhance ------- Enhance has a RrulerS tool that supports measurements and additionally provides angle data. The tool has over 80 mathematical filter variations: "Laplacian, medium noise filter", etc. Files can be saved as either TIFF, PICT, EPSF or text (however EPSF files can't be imported). MicroFrontier 7650 Hickman Road Des Moines, IA 50322 515-270-8109 Image Analyst ------------- An image processing product for users who need to extract quantitative data from video images. Image Analyst lets users configure sophisticated image processing and measurement routines without the necessity of knowing a programming language. It is designed for such tasks at computing number and size of cells in images projected by video cameras attached to microscopes, or enhancing and measuring distances in radiographs. Image Analyst provides users with an array of field-proven video analysis techniques that enable them to easily assemble a sequence of instructions to enhance feature appearance; count objects; determine density, shape, size, position, or movement; perform object feature extraction; and conduct textural analysis automatically. Image Analyst works with either a framegrabber board and any standard video camera, or a disk-stored image. Within minutes, without the need for programming, the Image Analyst user can set up a process to identify and analyze any element of a image. Measurements and statistics can be automatically or semi-automatically generated from TIFF or PICT files or from captured video tape images. Image Analyst recognizes items in images based on their size, shape and position. The tool provides direct support for the Data Translation and Scion frame grabbers. A menu command allows for image capture from a VCR video camera or other NTSC or PAL devices. There are 2 types of files, the image itself and the related Sequence file that holds the processing, measurements and analysis that the user defines. Automated sequences are set up in Regions Of Interest (ROI) represented by movable, sizable boxes atop the image. Inside a ROI, the program can find the distance between two edges, the area of a shape, the thickness of a wall, etc. Image Analyst finds the center, edge and other positions automatically. The application also provides tools so that the user can work interactively to find the edge of object. It also supports histograms and a color look-up table (CLUT) tool. Automatix, Inc. 775 Middlesex Turnpike Billerica, MA 01821 508-667-7900 IPLab ----- Signal Analytics Corp. 374 Maple Ave. E Vienna, VA 22180 703-281-3277 FAX 703-281-2509 "Menu-driven image processing software that supports 24-bit color or pseudocolor/grayscale image display and manipulation." MAP II ------ Among the Mac GIS systems, MAP II distributed by John Wiley has integrated image analysis. IMAGE ----- from Stanford : Try anonymous ftp from sumex-aim.stanford.edu It has pd source for image v2, and ready to run code for a mac under image v3. Windows/DOS PC-based tools ========================== CCD --- Richard Berry's CCD imaging book for Willamon-Bell contains (optional?) disks with image manipulating software. Source code is included. ERDAS ----- "ERDAS will do all of the things you want: rectification, classification, transformations (canned & user-defined), overlays, filters, contrast enhancement, etc. ... I was using it on my thesis & then changed the topic a bit & that work became secondary." ERDAS, Inc. 2801 Buford Highway Suite 300 Atlanta, GA 30329 404-248-9000 FAX 404-248-9400 RSVGA ----- "I have been getting up to speed on a program called RSVGA available from Eidetic Digital Image Ltd. in British Columbia. Its for IBM PC's or clones, cheap (about $400) and does all the stuff Erdas does but is not as fast or as powerful, though I have had only limited experience with Erdas. I have used RSVGA with 6 of 7 Landsat bands and it is a good starter program except for the obtuse manual" IMAGINE-32 ---------- It's a 32 bit package [I suppose for PCs] called "Imagine32" or "Image32" The program does a modest amount of image processing --add, subtract, multiply, divide, display, and plot an x or y cut across the image. It can also display a number of images simultaneously. The company is CompuScope, in Santa Barbara, CA. PC Vista -------- It was announced in the 1989 August edition of PASP. It is known to be available from Mike Richmond, whose email addresses have been richmond@bllac.berkeley.edu richmond@bkyast.berkeley.edu and his s-mail address is: Michael Richmond,Astronomy Department, Campbell Hall, Berkeley, CA 94720 The latest version of PC-Vista, version 1.7, includes not only the source code and help files, but also a complete set of executable programs and a number of sample FITS images. If you do wish to use the source code, you will need Microsoft C, version 5.0 or later; other compilers may work, but will require substantial modifications. To receive the documentation and nine double-density (360K) floppies (or three quad-density 3-1/2 inch floppies (1.44M) with everything on them, just send a request for PC-Vista, together with your name and a US-Mail address, to Office of Technology Licensing 2150 Shattuck Ave., Suite 510 Berkeley, Ca. 94704 Include a check (Traveller's Checks are fine) or purchase order for $150.00 in U.S. dollars, if your address is inside the continental U.S., or $165.00 otherwise, made out to Regents of the University of California to cover duplication and mailing costs. SOFTWARE TOOLS -------------- It's a set of software "tools" put out by Canyon State Systems and Software. They are not free, but rather cheap at about $30 I heard. It will handle most all of the formats used by frame grabber software. MIRAGE ------ It's image processing software written by Jim Gunn at the Astrophysics Dept at Princeton. It will run on a PC among other platforms. It is a Forth based system - i.e. a Forth language with many image processing displaying functions built in. DATA TRANSLATION SOURCE BOOK ---------------------------- The Data Translation company in Massachusetts publishes a free book containing vendors of data analysis hardware and software which is compatible with Data Translation and other frame grabbers. Surely you can find much more PC-related stuff in it. MAXEN386 -------- A couple of Canadians have written a program named MAXEN386 which does maximum entropy image deconvolution. Their company is named Digital Signal Processing Software, or something like that, and the software is mentioned in an article in Astronomy Magazine, either Jan or Feb 92 (an article on CCD's vs film). JANDEL SCIENTIFIC (JAVA) ------------------------ Another software package (JAVA) is put out by Jandel Scientific. Jandel Scientific, 65 Koch Road, Corte Madera, CA 94925, (415) 924-8640, (800) 874-1888. Microbrian ---------- Runs on an MS dos platform and uses a 32 bit graphics card (Vista), or an about to be released version will support a number of super VGA cards. Its a full blown remote sensed data processing system.. It is menu driven (character based screen), but is does not use a windowed user interface. Its is hardware protected with a dongle. Mbrian = micro Barrier reef Image Anaysis System. It was developed by CSIRO (Commonwealth Scientific & Industrial Organization) and is marketed/ supported by: MPA Australia (51 Lusher Road, Croydon, Victoria tel + 61 3 724 4488 fax +61 3 724 4455) There are educational and commercial prices, but be prepared to set aside $A10k for the first educational licence. Subsequent ones come cheaper (they need to!) It has installed sites worldwide. It is widely used at ANU. MicroImage ---------- The remote sensing lab here at Dartmouth currently uses Terra-Mar's MicroImage, on 486 PCs with some fancy display hardware. Terra-Mar Resource Information Services, Inc. 1937 Landings Drive Mountain View, CA 94043 415-964-6900 FAX 415-964-5430 Unix-based tools ---------------- IRAF (Image Reduction and Analysis Facility) -------------------------------------------- Developed in the National Optical Astronomy Observatory, Kitt Peak AZ It is free, you can ftp it from noao.edu and complement it with STSDAS from stsci.edu. Email to iraf@noao.edu for more details. Apparently this is one of the _de facto_ standards in the astronomical image community. They issue a newsletter also. They seem to support very well their users. Works with VMS also last I heard, and practically has its own shell on top of the VMS/Unix shells. It's suggested that you get a copy of saoimage for display under X windows. Very flexible/extendable -- tons (literally 3 linear feet) of documentation for the general user, skilled user, and programmer. ALV --- A Sun-specific image toolkit. Version 2.0.6 posted to comp.sources.sun on 11dec89. Also available via email to alv-users-request@cs.bris.ac.uk. AIPS ---- contact aipsmail@nrao.edu -- astronomical image processing system of the national radio astronomy observatory, Charlottesville, VA -- software distributed by 9 track tape last time I ordered it -- I did not find this package very useful -- tons of dense documentation -- very old code -- I heard in one of our astronomy laboratories the package may be rewritten completely in the near future -- major funding available. LABOimage 3.1 ------------- (version 4.0 soon for X11) It's written in C, and currently runs on Sun 3/xxx, Sun 4/xxx (OS3.5, 4.0 and 4.0.3) under SunView. The expert system for image segmentation is written in Allegro Common Lisp. It was used on the following domains: computer science (image analysis), medicine, biology, physics. It is distributed free of charge (source code). Available via anonymous FTP at ads.com (128.229.30.16), in pub/VISION-LIST-ARCHIVE/SHAREWARE/LaboImage_3.1.tar.Z Contact: Prof. Thierry Pun, Computer Vision Group Computing Science Center, U-Geneva 12, rue du Lac, CH-1207 Geneva SWITZERLAND Phone : +41(22) 787 65 82; fax: +41(22) 735 39 05 E-mail: pun@cui.unige.ch or pun@cgeuge51.bitnet Figaro ------ It was originally made for VMS, and can be obtained from Keith Shortridge in Australia (ks@aaoepp.aao.gov.au) and for Unix from Sam Southard at Caltech (sns@deimos.caltech.edu). It's about 110Mbytes on a Sun. KHOROS ------ Moved to the Scientific Visualization category below Vista ----- The "real thing" is available via anonymous ftp from lowell.edu. Email to vista@lowell.edu for more details. Total size less than 20Mbytes. DISIMP ------ (Device Independent Software for Image Processing) is a powerful system providing both user friendliness and high functionality in interactive times. Feature Description DISIMP incorporates a rich library of image processing utilities and spatial data options. All functions can be easily accessed via the DISIMP executive. This menu is modular in design and groups image processes by their function. Such a logical structure means that complicated processes are simply a progression through a series of modules. Processes include image rectification, classification (unsupervised and supervised), intensity transformations, three dimensional display and Principal Component Analysis. DISIMP also supports the more simple and effective enhancement techniques of filtering, band subtraction and ratioing. Host Configuration Requirements Running on UNIX workstations, DISIMP is capable of processing the more computational intensive techniques in interactive processing times. DISIMP is available in both Runtime and Programmer's environments. Using the Programmers environment, utilities can be developed for specific applications programs. Graphics are governed by an icon-based Display Panel which allows quick enhancments of a displayed image. Manipulations of Look Up Tables, colour stretches, changes to histograms, zooming and panning can be interactively driven through this control. A range of geographic projections enables DISIMP to integrate data of image, graphic and textual types. Images can be rectified by a number of coordinate systems, providing the true geographic knowledge essential for ground truthing. Overlays of grids, text and vector data can be added to further enhance referenced imagery. The system is a flexible package allowing users of various skill levels to determine their own working environment, including the amount of help required. DISIMP comes fully configured with no optional extras. The purchase price includes all functionality required for professional processing of remote sensed data.

Telephone: +61 3 825 5555 Fax: +61 3 826 6463 Global Imaging Software ----------------------- "We use Global Imaging Software to process AVHRR data, from the dish to the final display. Select a chunk of five band data from a pass, automatic navigation, calibrate it to Albedo and Temp, convert that to byte, register it to predesigned window, all relatively automatically and carefree. It has no classification routines to speak of, but it isn't that difficult to write your own with their programmer's module. Very small operation: one designs, one codes, one sells. Been around for a number of years, sold to Weather Service and Navy. Runs on HP9000 with HP-UX. Supports 24-bit display" HIPS ---- (Human Information Processing Laboratory's Image Processing System) Michael Landy co-wrote and sell a general-purpose package for image processing which has been used for basically all the usual image processing applications (robotics, medical, satellite, engineering, oil exploration, etc.). It is called HIPS, and deals with sequences of multiband images in the same way it deals with single images. It has been growing since we first wrote it, both by additions from us as well as a huge user-contributed library. Feature description HIPS is a set of image processing modules which together provide a powerful suite of tools for those interested in research, system development and teaching. It handles sequences of images (movies) in precisely the same manner as single frames. Programs and subroutines have been developed for simple image transformations, filtering, convolution, Fourier and other transform processing, edge detection and line drawing manipulation, digital image compression and transmission methods, noise generation, and image statistics computation. Over 150 such image transformation programs have been developed. As a result, almost any image processing task can be performed quickly and conveniently. Additionally, HIPS allows users to easily integrate their own custom routines. New users become effective using HIPS on their first day. HIPS features images that are self-documenting. Each image stored in the system contains a history of the transformations that have been applied to that image. HIPS includes a small set of subroutines which primarily deals with a standardized image sequence header, and a large library of image transformation tools in the form of UNIX ``filters''. It comes complete with source code, on-line manual pages, and on-line documentation. Host Configuration Requirements Originally developed at New York University, HIPS now represents one of the most extensive and flexible vision and image processing environments currently available. It runs under the UNIX operating system. It is modular and flexible, provides automatic documentation of its actions, and is almost entirely independent of special equipment. HIPS is now in use on a variety of computers including Vax and Microvax, Sun, Apollo, Masscomp, NCR Tower, Iris, IBM AT, etc. For image display and input, drivers are supplied for the Grinnell and Adage (Ikonas) image processors, and the Sun-2, Sun-3, Sun- 4, and Sun-386i consoles. We also supply user-contributed drivers for a number of other framestores and windowing packages (Sun gfx, Sun console, Matrox VIP-1024, ITI IP-512, Lexidata, Macintosh II, X windowing system, and Iris). The Hipsaddon package includes an interface for the CRS-4000. It is a simple matter to interface HIPS with other frame- stores, and we can put interested users in touch with users who have interfaced HIPS with the Arlunya and Datacube Max- Video. HIPS can be easily adapted for other image display devices because 98% of HIPS is machine independent. Availability HIPS has proven itself a highly flexible system, both as an interactive research tool, and for more production- oriented tasks. It is both easy to use, and quickly adapted and extended to new uses. HIPS is supplied on magnetic tape in UNIX tar format (either reel- to-reel or Sun cartridge), and comes with source code, libraries, a library of convolu- tion masks, and on-line documentation and manual pages.

Anyone to add here info? ========================================================================== 16. Image annotation software ----------------------------- a. Touchup runs in Sunview and is pretty good. It reads in rasterfiles, but even if your image isn't normally stored in rasterfile format you could use screendump to make it a rasterfile. b. Idraw (part of Stanford's InterViews distribution) can handle some image formats in addition to being a MacDraw like tool. I'm not sure exactly what they are. You can ftp the idraw's binary from interviews.stanford.edu. c. Tgif is another MacDraw like tool that can handle X11 bitmap (xbm) and X11 pixmap (xpm) formats. If the image you have is in formats other than xbm or xpm, you can get the pbmplus toolkit to convert things like gif or even some Macintosh formats to xpm. Tgif's sources are available in the pub directory on cs.ucla.edu (Version 2.12 of tgif at patchlevel 7 plus patch8 and patch9) d. Use the editimage facility of KHOROS (see below). This is just one utility in the overall system- you can essentially do all your image processing and macdraw-type graphics using this package. e.

The Explorer GUI allows users to build custom applications without having to write any, or a minimal amount of, traditonal code. Also, existing code can be easily integrated into the Explorer environment. Explorer currently is available now on SGI and Cray machines, but will become available on other platforms in time. [ Bundled with every new SGI machine, as far as I know] See comp.graphics.explorer for discussion of the package. There are also two FTP servers for related stuff, modules etc.: ftp.epcc.ed.ac.uk [129.215.56.29] swedishchef.lerc.nasa.gov [139.88.54.33] - mirror of the UK site apE --- Back in the 'old good days', you could get apE for nearly free.

A flow library allows graphs to employ broadcast, merge, synchronization, conditional, and sequencing control strategies. Users can easily extend WIT by defining new C functions, data types, and servers to access specialized hardware. They are currently sending out free 3.5" demo disks suitable for Sun Sparcstation floppy drives to anyone interested in trying out the software (and they are thinking about putting a copy of the demo for FTP).

In general, these codes are for US citizens only :-( XGRAPH ------ On the contrib tape of X11R5. Its specialty is display of up to 64 data sets (2D). NCAR ---- National Center for Atmospheric Research [ Anyone to add more info? ] IDL/PV-WAVE ----------- "The IDL/PV-WAVE software package is what I currently use . I/O is very simple (a major plus!!) & most of my programming is very short & sweet. Numerous output formats are available. there are certainly some minuses & it does require "programming". I use the command line version, though the "point & click" version is available...I have some acquaintances who use it on the Mac (I think via Mac-X). Basically, there are a lot of built-in functions, though some manipulation is required. IDL/PV-WAVE is able to work with any type of imagery. IDL runs on a unix system" IDL/SIPS -------- A lot of people are using IDL with a package called SIPS. This was developed at the University of Colorado (Boulder) by some people working for Alex Goetz. You might try contacting them if you already have IDL or would be willing to buy it. It's a few thousand dollars (American) I expect for IDL and the other should be free. Those are the general purpose packages I've heard of, besides what TerraMar has. SIPS _was_ written for AVIRIS imagery. I'm not sure how general purpose it is. You would have to contact Goetz or one of his people and ask. I have another piece of software (PCW) that does PC and Walsh transformations with pseudocoloring and clustering and limited image modification (you can compute an image using selected components). I've used it on 70 megabyte AVIRIS images without problems, but for the best speed you need an external DSP card. It will work without it, but large images take quite a while (50-70 times as long) to process. That's a freebie if you want it. My favorite is IDL (Interactive Data Language) from Research Systems, Inc. IDL is in my opinion, much better and infinitely easier. Its programming language is very strong and easy -- very Pascal-like. It handles the number-crunching very well, also. Personally, I like doing the number-crunching with IDL on the VAX (or Mathematica, Igor, or even Excel on the Mac if it's not too hairy), then bringing it over to NIH Image for the imaging part. I have yet to encounter any situation which that combination couldn't handle, and the speed and ease of use (compared to IRAF) was incredible. By the way, it's mostly astronomical image processing which I've been doing. This means image enhancement, cleaning up bad lines/pixels, and some other traditional image processing routines. Then, for example, taking a graph of intensity versus position along a line I choose with the mouse, then doing a curve fit to that line (which I might do like in KaleidaGraph.) [ For IDL call Research Systems , for PV-WAVE call Precision Visuals and for SIPS call University of Colorado @ Boulder . From what I can understand, you can get packaged programs from Research Systems, though -- nfotis ] Visual3 ------- contact Robert Haimes, MIT FieldView --------- Intelligent Light Corp. ========================================================================== 18. Molecular visualization stuff --------------------------------- [ Based on a list from cristy@dupont.com < Cristy > , which asked for systems for displaying Molecular Dynamics, MD for short ] Flex ---- It is a public domain package written by Michael Pique, at The Scripps Research Institute, La Jolla, CA. Flex is stored as a compressed, tar'ed archive (about 3.4MB) at perutz.scripps.edu [137.131.152.27], in pub/flex. It displays molecular models and MD trajectories. MacMolecule ----------- (for Macintosh). I searched with Archie, and the most promising place is sumex-aim.stanford.edu (info-mac/app, and info-mac/art/qt for a demo) MD-DISPLAY ---------- Runs on SGI machines. Call Terry Lybrand (lybrand@milton.u.washington.edu). XtalView -------- It is a crystallography package that does visualize molecules and much more. It uses the XView toolkit. Call Duncan McRee <dem@scripps.edu> landman@hal.physics.wayne.edu: ----------------------------- I am writing my own visualization code right now. I look at MD output (a specific format, easy to alter for the subroutine) on PC's. My program has hooks into GKS. If your friend has access to Phigs for X (PEX) and fortran bindings, I would be happy to share my evolving code (free of charge). Right now it can display supercells of up to 65 atoms (easy to change), and up to 100 time steps, drawing nearest neighbor bonds between 2 defining nn radii. It works acceptably fast on a 10Mhz 286. icsg0001@caesar.cs.montana.edu: ------------------------------ I did a project on Molecular Visualization for my Master's Thesis, using UNIX/X11/Motif which generates a simple point and space-filling model.

A friend of mine and I have developed a program to display an MD run dynamically on Silicon Graphics. We are working to improve it, but it doesn't work under X, we are using the graphi. lib. of the Silicon Gr. because they are much faster then X. When we'll end it we'll post on the news info about where to get it with ftp. (Will be free software). XBall V2.0 ---------- Written by David Nedde. Call daven@maxine.wpi.edu. XMol ---- An X Window System program that uses OSF/Motif for the display and analysis of molecular model data. Data from several common file formats can be read and written; current formats include: Alchemy, CHEMLAB-II, Gaussian, MOLSIM, MOPAC, PDB, and MSCI's XYZ format (which has been designed for simplicity in translating to and from other formats). XMol also allows for conversion between several of these formats. Xmol is available at ftp.msc.edu. Read pub/xmol/README for further details. INSIGHT II ---------- from BIOSYM Technologies Inc. SCARECROW --------- The program has been published in J. Molecular Graphics 10 (1992) 33. The program can analyze and display CHARMM, DISCOVER, YASP and MUMOD trajectories. The program package contains also software for the generation of probe surfaces, proton affinity surfaces and molecular orbitals from an extended Huckel program. It works on Silicon Graphics machines. Contact Leif Laaksonen <Leif.Laaksonen@csc.fi or laaksone@csc.fi> [ I would also suggest looking at least in SGI's Applications Directory. It contains many more packages - nfotis ] ========================================================================== 19. GIS (Geographical Information Systems software) --------------------------------------------------- [ I wish to put under this title and the mainly Remote Sensing software that's presently under Subject 15: Image analysis software - Image processing and display . Any ideas?? ] GRASS ----- (Geographic Resource Analysis Support System) of the US Army Construction Engineering Research Lab (CERL). It is a popular geographic and remote sensing image processing package. Many may think of GRASS as a Geographic Information System rather than an Image Processing package, although it is reported to have significant image processing capabilities. Feature Descriptions I use GRASS because it's public domain and can be obtained through the internet for free. GRASS runs in Unix and is written in C. The source code can be obtained through an anonymous ftp from the Office of Grass Integration. You then compile the source code for your machine, using scripts provided with GRASS. I would recommend GRASS for someone who already has a workstation and is on a limited budget. GRASS is not very user-friendly, compared to Macintosh software." A first review of overview documentation indicates that it looks useful and has some pixel resampling functions not in other packages plus good general purpose image enhancement routines (fft). Kelly Maurice at Vexcel Corp. in Boulder, CO is a primary user of GRASS . This gentleman has used the GRASS software and developed multi-spectral (238 bands ??) volumetric rendering, full color, on Suns and Stardents. It was a really effective interface. Vexcel Corp. currently has a contract to map part of Venus and convert the Magellan radar data into contour maps. You can call them at (303) 444-0094 or email care of greg@vexcel.com 192.92.90.68 Host Configuration Requirements If you are willing to run A/UX you could install GRASS on a Macintosh which has significant image analysis and import capabilities for satellite data. GRASS is public-domain, and can run on a high-end PC under UNIX. It is raster-based, has some image-processing capability, and can display vector data (but analysis must be done in the raster environment). I have used GRASS V.3 on a SUN workstation and found it easy to use. It is best, of course, for data that are well represented in raster (grid-cell) form. Availability CERL's Office of Grass Integration (OGI) maintains an ftp server: moon.cecer.army.mil (129.229.20.254). Connections are only allowed during off- peak hours (weekends and weekdays before 8:00 A.M. and after 5:00 P.M. Central Standard time). Mail regarding this site should be addressed to grass-ftp-admin@moon.cecer.army.mil. This location will be the new "canonical" source for GRASS software, as well as bug fixes, contributed sources, documentation, and other files. This FTP server also supports dynamic compression and uncompression and "tar" archiving of files. A feature attraction of the server is John Parks' GRASS tutorial. Because the manual is still in beta-test stage, John requests that people only acquire it if they are willing to review it and mail him comments/corrections. The OGI is not currently maintaining this document, so all correspondence about it should be directed to grassx@tang.uark.edu Support Listserv mailing lists: grassu-list@amber.cecer.army.mil (for GRASS users; application-level questions, support concerns, miscellaneous questions, etc) Send subscribe commands to grassu-request@amber.cecer.army.mil. grassp-list@amber.cecer.army.mil (for GRASS programmers; system-level questions and tips, tricks, and techniques of design and implementation of GRASS applications) Send subscribe commands to grassp-request@amber.cecer.army.mil. Both lists are maintained by the Office of Grass Integration (subset of the Army Corps of Engineers Construction Engineering Research Lab in Champaign, IL). The OGI is providing the lists as a service to the community; while OGI and CERL employees will participate in the lists, we can make no claim as to content or veracity of messages that pass through the list. If you have questions, problems, or comments, send E-mail to lists-owner@amber.cecer.army.mil and a human will respond. Microstation Imager ------------------- Intergraph (based in Huntsville Alabama) sells a wide range of GIS software/hardware. Microstation is a base graphics package that Imager sits on top of. Imager is basically an image processing package with a heavy GIS/remote sensing flavor. Feature Description Basic geometry manipulations: flip, mirror, rotate, generalized affine. Rectification: Affine, 2nd, 3rd, 4th and 5th order models as well as a projective model (warp an image to a vector map or to another image). RGB to IHS and IHS to RGB conversion. Principal component analysis. Classification: K-means and isodata. Fourier Xforms: Forward, filtering and reverse. Filters: High pass, low pass, edge enhancing, median, generic. Complex Histogram/Contrast control. Layer Controller: manages up to 64 images at a time -- user can extract single bands from a 3 band image or create color images by combining various individual bands, etc. The package is designed for a remote sensing application (it can handle VERY LARGE images) and there is all kinds of other software available for GIS applications. Host Configuration Requirements It runs on Intergraph Workstations (a Unix machine similar to a Sun) though there were rumors (there are always rumors) that the software would be ported to PC and possibly a Sun environment. PCI --- A company called PCI, Inc., out of Richmond Hill, Ontario, Canada, makes an array of software utilities for processing, manipulation, and use of remote sensing data in eight or ten different "industry standard" formats: LGSOWG, BSQ, LANDSAT, and a couple of others whose titles I forget. The software is available in versions for MS-DOS, Unix workstations (among them HP, Sun, and IBM), and VMS, and quite possibly other platforms by now. I use the VMS version. The "PCI software" consists of several classes/groups/packages of utilities, grouped by function but all operating on a common "PCI database" disk file. The "Tape I/O" package is a set of utility programs which read from the various remote-sensing industry tape formats INTO, or write those formats out FROM, the "PCI database" file; this is the only package I use or know much about. Other packages can display data from the PCI database to one or another of several PCI-supported third-party color displays, output numeric or bitmap representation of image data to an attached printer, e.g. an Epson-type dot-matrix graphics printer. You might be more spe- cifically interested in the mathematical operations package: histo- gram and Fourier analysis, equalization, user-specified operations (e.g. "multiply channel 1 by 3, add channel 2, and store as channel 5"), and God only knows what all else -- there's a LOT. I don't have and don't use these, so can't say much about them; you only buy the packages your particular application/interest calls for. Each utility is controlled by from one to eight "parameters," read from a common "parameter file" which must be (in VMS anyway) in your "default directory." Some utilities will share parameters and use the same parameter for a different purpose, so it can get a bit confusing setting up a series of operations. The standard PCI environment contains a scripting language very similar to IBM-PC BASIC, but which allows you to automate the process of setting up parameters for a common, complicated, lengthy or difficult series of utility executions. (In VMS I can also invoke utilities independently from a DCL command procedure.) There's also an optional programming library which allows you to write compiled language programs which can interface with (read from/write to) the PCI data structures (database file, parameter file). The PCI software is designed specifically for remote-sensing images, but requires such a level of operator expertise that, once you reach the level where you can handle r-s images, you can figure out ways to handle a few other things as well. For instance, the Tape I/O package offers a utility for reading headerless multi-band (what Adobe PhotoShop on the Macintosh calls "raw") data from tape, in a number of different "interleave" orders. This turns out to be ideal for manipulating the graphic-arts industry's "CT2T" format, would probably (I haven't tried) handle Targa, and so on. Above all, however, you HAVE TO KNOW WHAT YOU'RE DOING or you can screw up to the Nth degree and have to start over. It's worth noting that the PCI "database" file is designed to contain not only "raster" (image) data, but vectors (for overlaying map information entered via digitizing table), land-use, and all manner of other information (I observe that a remote-sensing image tape often contains all manner of information about the spectral bands, latitude, longitude, time, date, etc. of the original satellite pass; all of this can go into the PCI "database"). I _believe_ that on workstations the built-in display is used. On VAX systems OTHER than workstations PCI supports only a couple of specific third-party display systems (the name Gould/Deanza seems to come to mind). One of MY personal workarounds was a display program which would display directly from a PCI "database" file to a Peritek VCT-Q (Q-bus 24-bit DirectColor) display subsystem. PCI software COULD be "overkill" in your case; it seems designed for the very "high end" applications/users, i.e. those for whom a Mac/PC largely doesn't suffice (although as you know the gap is getting smaller all the time). It's probably no coincidence that PCI is located in Canada, a country which does a LOT of its land/resource management via remote sensing; I believe the Canadian government uses PCI software for some of its work in these areas. SPAM (Spectral Analysis Manager) -------------------------------- Back in 1985 JPL developed something called SPAM (Spectral Analysis Manager) which got a fair amount of use at the time. That was designed for Airborne Imaging Spectrometer imagery (byte data, <= 256 pixels across by <= 512 lines by <= 256 bands); a modified version has since been developed for AVIRIS (Airborne VIsual and InfraRed Imaging Spectrometer) which uses much larger images. Spam does none of these things (rectification, classification, PC and IHS transformations, filtering, contrast enhancement, overlays). Actually, it does limited filtering and contrast enhancement (stretching). Spam is aimed at spectral identification and clustering. The original Spam uses X or SunView to display. The AVIRIS version may require VICAR, an executive based on TAE, and may also require a frame buffer. I can refer you to people if you're interested. PCW requires X for display.
