Abstract: Fingerprinting a video including video frames is disclosed. A method includes receiving the video, generating sub-images, generating sub-fingerprints for the video using the sub-images, and matching the video to a reference video using the sub-fingerprints. Generating sub-images includes, for a video frame of some of the video frames, generating a binary image for the video frame, identifying a first region of the binary image, and identifying a sub-image of the video frame that is co-extensive and co-located with the first region of the binary image. A pixel of the video frame is identified in the binary image by a first value or a second value where the first value indicates a motion pixel and the second value indicates a still pixel. The first region includes more of the first value than the second value, and the first region is indicative of a motion in the video frame.
