Image comparison module for PHP

Question

Is there any basic (free or not), but usable - not like libpuzzle - image fingerprinting/similarity/compare module for PHP, which works akin to TinEye or Google image upload search? It's basically needed to avoid uploading almost the same (but with watermarks, resized etc.) image twice into a set of 50-300 images.

This is a very interesting educational article about image comparison. It wouldn't be hard at all to adapt to PHP using the GD library or ImageMagick.
