Andrew Derek, Morris Octavius John: Motion vector estimation, motion picture encoding and storage.. Philips Electronics, Philips, April 7, 1993: EP0535746-A2 (79 worldwide citation)

In the encoding of a frame (P3) in a digitised motion picture sequence, the frame is divided into blocks (A) of pixels and a motion vector (VA) found to predicts the contents of each block A from a block (A') in a previous frame (IO). Rather than evaluate many thousands of candidate vectors to find ...
