说明：
最简单的差分格式有向前、向后和中心3种。
向前差分：f (n)=f(n+1)-f(n)
向后差分：f (n)=f(n)-f(n-1)
中心差分：f (n)=[f(n+1)-f(n-1)]/2(The easiest difference format forward, backward, and three kinds of centers.
Forward differencing: f (n) = f (n+ 1)-f (n)
Backward difference: f (n) = f (n)-f (n-1)
Central difference: f (n) = [f (n+ 1)-f (n-1)]/2)

corner_test
拐点的检测，对一个图像的拐点进行检测，使用的是freeman链码的方法，检测图像中拐点的方向，确定该方向是不是拐点。(Inflection point detection, an image of the inflection point for testing, use freeman chain code method, testing the image in the direction of the inflection point, we determine the direction is inflection point.
