  • Fingerprinting to match videos having varying aspect ratios
    Patent number: 8947595
    Abstract: A combined fingerprint is generated for a video that can match two near-identical videos that differ only in their aspect ratios or formats. A transformation strategy is selected by selecting a first and a second aspect correction method. A first transformed video is generated by applying the first aspect correction method to the video. A second transformed video is generated by applying the second aspect correction method to the video. A first fingerprint is generated using the first transformed video. A second fingerprint is generated using the second transformed video. The combined fingerprint is generated by combining the first half of the first fingerprint with the second half of the second fingerprint.
