Abstract: A method of finding a match in a match database with a target media includes receiving a target media item, wherein the target media item comprises one or more pictures or videos, extracting multiple visual descriptors from the target media item, formulating descriptor vectors from the multiple visual descriptors, reducing the dimension of the descriptor vectors to generate projected descriptors, creating cluster keys from the projected descriptors, and generating a list of a number of matches by comparing the cluster keys of the target media item with keys of sequences stored in the matching database.
