Frame based video matching |
摘要 |
A method for identifying videos within a corpus of reference videos that match a query video is presented. The method includes receiving an input search criteria including search and matching parameters. The method includes indexing each reference video frame by frame and determining a visual signature based on visual signatures of all frames or a subset of frames. The method also includes determining a visual signature of the query video and comparing the visual signatures of each reference video to the query video and identifying matches. In one embodiment, indexing includes determining subsets of frames within each reference video including anchor, heart beat and key frames. A primary visual signature is based on the visual signatures of all frames within the reference video. A secondary visual signature is based on the visual signatures of at least one of the subsets within the reference video.
