USAGE: fitcrit infile outimg [-l FIT_LENGTH] [-r CORNER_ARC] [-c] [-L]
fitcrit fits straight lines between critical points
(curvature maxima) in the segments of pixel chains;
corners are located at the location of intersection of their
two boundary lines; curves are located by two straight lines
drawn from curve onsets (transition points) to the middle
point in the arc of the curve.
ARGUMENTS:
infile: input filename (PCC)
outimg: input image filename (TIF)
OPTIONS:
-l FIT_LENGTH: is the arc-length of the fit along the data
segments; the longer is this length, the greater is
smoothing, but the less ability to fit small features;
this is usually chosen as the minimum arc-length between
critical points on the data.
(default = 13 [connected pixels]. minimum is 5.)
-r CORNER_ARC: maximum arc-length of a corner; since a
corner feature will usually be rounded, there is a maximum
arc-length before over which that feature is considered
a curve and not a corner. (default = 3 [connected pixels].
-c: when set, prints out the (x,y) coordinates of the
straight-line fits between critical points.
