对于较粗的样本点集 hough 算法是不可能做到检测全部直线的. 另一方面 hough 还会测出许多不存在的直线. 在应用的时候只能根据需要自己标定 精度.



以下是我在MATLAB下开发的hough函数 输入一个灰度图形矩阵, 返回 最长直线斜率. 用来做图形倾斜校正的. 希望贴出来还能有点用吧~-For a sample point set coarse algorithm hough it is not possible to do all the straight line detection. Hough will be measured on the other hand, much of the straight line does not exist. At a time when the application can only be based on the needs of calibration accuracy of their own. The following is in my MATLAB hough function developed under a gray-scale graphics input matrix, the slope of a straight line back up. to make graphics tilt correction. I hope it can paste a bit with it ~
