matlab 边界跟踪程序，图像要求为二值图像，输出为边界的点的坐标。-matlab boundary tracking procedure, the image requested for the binary image, the output for the coordinates of border points.

对二值图像边界进行跟踪，对边缘进行判断，然后沿着边缘进行跟进- C = CONTOUR_FOLLOWING(BW) takes BW as an input. BW is a binary array containing the image of an object ( 1 : foreground, 0 : background). It returns a circular list (N x 2, C(1,:)
