cmptiff [options] IMAGE1 IMAGE2
cmptiff takes two TIFF images and outputs the difference, according to the options described below.
absolute threshold of acceptable error, specified as:
relative acceptable error heuristic tests:
o = acceptable number of outliers, small integer number of samples allowed to be above 'threshold' without triggering an error
e = egregious error window, fractional threshold increment above threshold; any single sample difference above theshold+e classifies the images as significantly different, independent of o.
For float images, -d .125 is like -t .125
For 8-bit images, -d 32 is like -t .125
A fuzzy test of images from different platforms might be:
-t .001 -m .3 -x 2,.1
