hough变换是对图像进行预处理后，提取角点的算法。希望这段代码可以很好帮到大家，-hough transform of images after pretreatment Corner extraction algorithms. I hope this code can be a good help to you,

Hough变换及其扩展算法，在图像处理领域应用广泛，值得仔细研究-Hough transform and its expansion algorithm, widely used in image processing, it is worth careful study

霍夫变换可以检测直线，矩形和圆，这里是检测圆形程序，很不错(Hough transform can detect lines, rectangles and circles, here is the detection of circular procedures, very good)
