摘　　要：提出了一种能快速有序搜索边界点的新方法 ,通过比较任一起始边界点S与周边 8个像素点Pfi的值 ,实现按顺时针方向自动识别边界点并记录其坐标。该方法具有编程简单且仅在最小范围局部搜索边界点的特点 。A new method which can quickly and orderly search the figure boundary spot is proposed. To automatically recognize the boundary spot and to record the coordinate in a clockwise direction are realized through the comparison of the value between the starting randomly boundary spot 'S' and 8 pixels Pfi around 'S'. This method has the character which can program easily and partly search the boundary spot at the minimal range and can overcome the disadvantage of large amount of computation, which the normal method has by overall situation search.
