摘要：This paper presents a stereo-matching algorithm to establish reliable correspondence between images by selecting a desirable window size for SAD (Sum of Absolute Differences) computation. In SAD computation, a degree of parallelism between pixels in a window changes depending on its window size, while a degree of parallelism between windows is predetermined by the input-image size. Based on this consideration, a window-parallel and pixel-serial architecture is proposed to achieve 100% utilization of processing elements. Not only 100% utilization but also a simple interconnection network between memory modules and processing elements makes the VLSI processor much superior to conventional processors.
