Abstract: The Shazam algorithm has proven its reliability and efficiency in audio identification tasks. In this paper, we adapt the core principles of the Shazam algorithm for the problem of partial video copy detection. We propose a novel method for alignment video fingerprints in partial copy detection search of video query across video base. One of the best features of this method: fast CPU execution, simplicity and at the same time high efficiency. Experimental results on publicly available video datasets demonstrate that our approach achieves high accuracy in detecting partial and modified video copies, with competitive performance in terms of speed and scalability. Our findings suggest that Shazam-inspired fingerprinting can serve as an effective tool for large-scale video copy detection applications.
