图片使用matlab做处理，有均值滤波器处理、LoG算子提取图像边缘、hough变换提取直线、二值化处理后。-Image processing using matlab to do with mean filter processing, LoG operator to extract image edge, hough transform to extract straight, binarization processing.

matlab代码用来实现霍夫变换检测直线，比较好哦用。-matlab code used to implement the Hough transform to detect straight lines, with more Ay.
