image_match_tso is a simple package for finding approximate image matches from a
corpus. It is similar, for instance, to pHash <http://www.phash.org/>, but
includes a database backend that easily scales to billions of images and
supports sustained high rates of image insertion: up to 10,000 images/s on our
cluster!
