中文说明：霍夫变换是图像处理中从图像中识别几何形状的基本方法之一，应用很广泛，也有很多改进算法。最基本的霍夫变换是从黑白图像中检测直线(线段)。内含霍夫变换代码，需要注意的是需要将输入图像路径修改一下，生成经过二值化处理之后得到的直线特征图。
English Description：
Hough transform is image processing recognition from an image in one of the basic geometrical shapes, very broad, there are many improvements in algorithms. Basic detection Hough transform is from a black and white image line (segment). Includes Hough transform code, be noted that need to modify input images path, generated after binarization processing got the line feature.
