发明名称 Identifying video content via fingerprint matching
摘要 Methods and systems to identify video content based on video fingerprint matching are described. In some example embodiments, the methods and systems generate a query fingerprint of a frame of video content captured at a client device, query a database of reference fingerprints, determine the query fingerprint of the frame of captured video content matches a reference fingerprint, and identify the video content based on the match of fingerprints.

主权项 1. A computer-implemented method, comprising: accessing a query fingerprint of a single video frame of video content captured at a client device, the query fingerprint being generated based on a first value of a first spatial region within the single video frame of video content, the first value of the first spatial region being calculated by subtracting a spatial sub-region of the first spatial region from one or more other spatial sub-regions of the first spatial region; querying a database of reference fingerprints associated with video frames of known video content, each of the reference fingerprints being generated based on spatial regions within a different single video frame of the known video content; determining that the query fingerprint matches at least one of the reference fingerprints; and identifying the video content captured at the client device based on the determination that the query fingerprint matches at least one of the reference fingerprints.
