New method of parallel processing for boundary tracking

Abstract: Aiming at the complex question of edge tracing,this paper presents a new system parallel mode with parallel data and parallel processing. In image preprocessing the new system realizes Robeters operator and image segmentation in real time. In image tracing this system realizes the chain code edge tracing in real time. In hardware structure this system adopts the function pipeline methods to integrate the image capture, preprocessing and edge tracing into one system, and realizes high speed edge tracing. This paper discusses the theory of parallel data accessing, introduces the whole system structure and the method of parallel preprocessing and edge tracing, and also offers some examples of edge tracing.
