摘要:
Methods and systems for searching for and retrieving video content via fingerprint matching are described. In some example embodiments, the methods and systems access an index of reference fingerprints, such as quantized values associated with multiple values calculated from patches of a frame, that are associated with sequential frames of known video content. The methods and systems may receive a search query that includes a group of query fingerprints associated with sequential frames of video content presented at a client device, access the index, compare the group of query fingerprints to reference fingerprints of the index, determine that the group of query fingerprints match the reference fingerprints of the index, and identify the video content presented at the client device based on the determined match.
