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.
