A note about the drawing : this drawing illustrates the basic
principle behind Video Signature, the technique used in this
search engine to summarize each video. The v's and w's represent
video frames from two visually similar video sequences. The
video signature for each video consists of the frames that are
closest to a small set of random vectors such as s1 and s2. It
can be shown that by comparing the corresponding frames in two
video signatures, the fraction of similar frames between two
video sequences can be reliably measured.
