[QUOTE="Ed Snible, post: 4726593, member: 82322"]How do humans cope with those factors? No one yet knows how well computer programs will deal with all those differences, because the programs have only been tested on a few coins. Yet the early results are impressive. The ANS' CADS program got the correct match in at least one case where the human expert got it wrong. The computer vision approaches merely locate "features", or interesting edges and curves, and count matching features on different specimens. Die shift, graffiti, countermarks, and planchet problems add more "features". If you have 50 coins you can do the die study on your own. If you have 3000 owls the computer can sort them by the number of matches. Suppose the computer says the most similar pair has 80% matching "features".
