Finding repeated images - part 1 - Vector Similarity Measures
Wednesday, July 16th, 2008I’ve been playing around with spatial matching on clker.com . My goal was to figure out whether an image being submitted already exists or not, and to do that very fast. Titles, tags and all information in the image can change, so basically they are useless when it comes to know whether an image is repeated with high confidence. What is really needed is a set of features, that can be extracted fast enough and stored in the database, and indexed in a practically searchable manner.
