Three-dimensional wavelet based video fngerprinting
US8340449B1 Patents
A method and system generates and compares fingerprints for videos in a video library. The video fingerprints provide a compact representation of the spatial and sequential charac teristics of the video that can be used to quickly and efficiently identify video content. Because the fingerprints are based on spatial and sequential characteristics rather than exact bit sequences, visual content of videos can be effectively com pared even when there are small differences between the Videos in compression factors, source resolutions, start and stop times, frame rates, and so on. Comparison of vide
