examine differences between two images


This utility examines the differences between two images. It produces a visual annotation and reports statistics.

It is optimised for images which come from browser screenshots. It analyses the image for vertical motion, and annotates connected regions that have the same vertical displacement. Then it highlights any remaining ("residual") differences which are not explained by vertical motion on a pixel-by-pixel basis.
