Claims28
A method for receiving input video comprising a sequence of input video frames, and producing a compact video signature as an identifier of said input video, comprising the steps of:
- generating a processed video tomograph using an arrangement of corresponding lines of pixels from the respective frames of the sequence of video frames;
- measuring characteristics of the processed video tomograph;
- and
- producing said video signature from said measured characteristics.
A method for identifying an input video clip as substantially matching or not matching with respect to archived video clips, comprising the steps of:
- producing, for each video clip to be archived, an archived video signature from a processed video tomograph of said video clip;
- producing, for said input video clip, an input video signature from a processed video tomograph of said video clip;
- comparing said input video signature to at least one of said archived video signatures;
- and
- identifying the input video clip as substantially matching or not matching archived video clips depending on the results of said comparing.
