USAGE: structfeat infile [-s] [-L]

structfeat lists line structures, that is, objects
made up of one or many connected line segments.

ARGUMENTS:
    infile: input filename (PCC)

OPTIONS:
        -s: print summary only.
        -L: print Software License for this module
 

Example:

structfeat eTH.pcc

eTH.pcc: (generated by running thin e.tif eTH.tif, followed by pcc eTH.tif eTH.pcc)

Binary file (not displayable)

output:

image size: 36x36, PCC length = 37
4 level 1 line features
