Distance between frames. Normalized distance between frame 4263 and all other frames () in a video. The most similar frames are the ones with minimum distance. The three most similar to frame 4263 are frames 2879, 5989 and 7020. The grey arrows show the frame most similar to 4263 in each period. The semi-periodic nature of the video makes it possible to find similar frames faster.
