USAGE: hough inimg outimg [-b BORDER] [-d] [-L]

hough transforms binary image from
spatial domain ((x,y) coordinates) to polar coordinate
domain ((rho, theta) coordinates); peak in the polar
("Hough")domain indicates a dominant line in the spatial domain;
NOTE: origin (0,0) of Hough transform
      image is in top-left corner;
      rho increases along horizontal axis to
      maximum rho equal to image diagonal length;
      theta increases downward from 0 radians to PI radians.

ARGUMENTS:
    inimg: input image filename (TIF)
   outimg: output image filename (TIF)

OPTIONS:
  -b BORDER: to remove noise at borders of image by omitting
             image for this number of rows/cols [default = 2].
         -d: display peak in Hough transform space.
         -L: print Software License for this module
 
 

Example:

hough houghIn.tif houghOut.tif -d
