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)。-Hough transform image processing image recognition from the basic geometry of one of the methods, the application is very wide, there are many improved algorithm. The most basic black and white images from the Hough transform to detect straight lines (line).
