Hi QA gurus!

Somebody out there that can point me to an AFP (a page describing language) comparision tool? A tool (prefereably that runs on both WIN and Unix) that as input takes 1. an oracle image file and 2. a test image file and then outputs a (numeric) value representing the proximity or "resemble-ness" between the both images.

I.e. not a simple binary- or ascii-text comparison tool but an image comparision.

Thank you, [img]/images/graemlins/cool.gif[/img]
