这个程序可以识别图像中的线段或者直线，算法采用哈夫变换，将直线变换为另一个坐标系中的点，进而完成识别。-this procedure can identify the image or straight line segments, Hough transform algorithm. Linear transformation of coordinate system to another's point, thus completing the identification.

利用hough变换来进行圆形检测.Function uses Standard Hough Transform to detect circles in a binary image.According to the Hough Transform for circles, each pixel in image space corresponds to a circle in Hough space and vise versa. upper left corner of image is t
