The Image Compare project provides two applications. The Image Compare application (imagecomp) is a tool to aid the visual comparison of two coin images. The Image Mask command line application prepares coin images for publication.
Useful and exacting! The controls take a little to figure out, but once you do this download contains two very useful tools. One for comparing two images (two examples of a particular type of coin for example - letting you easily find any differences in the dies) and one for cropping to round objects (like coins or medals where you want to neatly mask out the background). Many thanks to the developer!
hard to use, don't what the button means?
