Hough变换

该函数用于对检测图像中的平行直线。如果图像中有两条平行的直线，则将这两条平行直线提取出来。



要求目标图像为只有0和255两个灰度值的灰度图像。-Hough transform of the function is used to detect the image of parallel lines. If the image there are two parallel lines, two parallel lines will be extracted. Requires the target image for the only two gray values 0 and 255 gray image.
