image_match 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!
Based on the paper An image signature for any kind of image, Goldberg et al <http://www.cs.cmu.edu/~hcwong/Pdfs/icip02.ps>.
