Abstract:
1. A method comprising: generating, by a device comprising a processor, a set of image classifiers that classify images according to characteristics of the images, wherein the generating comprises: classifying a set of candidate images using the set of image classifiers to generate fingerprints for the set of candidate images, wherein a fingerprint comprises a plurality of segments; representing the plurality of segments of the fingerprints for the set of candidate images using a plurality of hash tables; classifying a target image using the set of image classifiers to generate a fingerprint of the target image; comparing a plurality of segments of the fingerprint of the target image with the plurality of segments of the fingerprints for the set of candidate images using the plurality of hash tables; and selecting a candidate image having a defined level of similarity with the target image based on the comparing.
