What is Fast Image Retrieval for Diamonds about?
This document proposes a hierarchy of classifiers to efficiently match diamond images in a large database despite significant variations. It begins with a coarse classifier that applies a wavelet transform to image histograms, rejecting 99.9% of non-matches. The remaining candidates are then processed by more complex classifiers with exact matching algorithms specialized for diamond images using their unique properties. This coarse-to-fine approach successively prunes the database to identify matching diamo
