Perceptual Image Diff
Description
PerceptualDiff is an image comparison utility that compares two images using a perceptual metric. That is, it uses a computational model of the human visual system to determine if two images are visually different, so minor changes in pixels are ignored.

Excellent small program to help evaluate the perceptible difference between images. We even use it for evaluation of video codecs in our studio.
