Abstract
A method and system for generating a fingerprint for a video object. The method includes obtaining a plurality of frames associated with a video object. Additionally, the method includes, for each of the plurality of frames, processing information associated with the plurality of frames, determining a plurality of spatial signatures for the each of the plurality of frames based on at least information associated with the each of the plurality of frames, and determining a plurality of temporal signatures for the each of the plurality of frames based on at least information associated with the plurality of frames. The plurality of spatial signatures corresponds to a plurality of resolutions respectively, and the plurality of temporal signatures corresponding to a plurality of frame rates respectively.
