Abstract

A video stream processing system comprising a novel modular family of image processing and pattern recognition submodules, the submodules utilize a unique system signalling and interface protocol, and thus can be cascaded and paralleled to produce complex special purpose image processing systems which can operate at video or near video data rates. A stream of digitized pixel data is pipelined through a variety of submodules to support a wide variety of image processing applications. A common video interface provides for handling pixel data in the video signal path and a processor interface allows communication to any modern microprocessor for overall system control, for optional addition image processing and for defining options within each submodule.
