Lancelot Wu, Kun Min Yang: Circuit implementation of block matching algorithm. Bell Communications Research, James W Falk, January 30, 1990: US04897720 (48 worldwide citation)

A circuit for implementing a full search block matching algorithm for coding video signals sequentially receives pixel values from a block of pixels in a current video frame and sequentially receives pixel values from a search area of a previous video frame. The circuit includes a plurality of proce ...
