Moravec角点检测算法将角点定义为具有低“自相关性”的点。算法会检测图像的每一个像素，将像素周边的一个邻域作为一个patch，并检测这个patch和周围其他patch的相关性。-Moravec corner detection algorithm to corner points defined as having a low "autocorrelation" point. Algorithm detects images of each pixel, the pixel as a neighborhood around a patch, and detects the patch and the patch around the other correlation.
