【Abstract】 A series of key problems about the binary image profiled processing, including mainly the parallel pre processing, the chain code tracing, the directional chain code recording and the smoothing process are discussed. Parallel pre processing uses the bits processing ability of the logical operation. It could implement parallel processing of several sample points, and the speed is much faster than that of any other pre processing. Chain code tracing can quickly and easily get the whole contour information in one tracing. The directional chain code is used to record the contour information data according to the trend of the contour, and this will be very convenient for the smoothing process later on.更多还原
