Randomized Hough Transform with Imitative Gradient Direction
采用拟梯度方向信息的随机Hough变换直线检测

To solve the problem of inefficient sampling and accumulation in RHT,the concept of imitative gradient di- rection (IGD)is proposed based on the gradient direction information of image edge.With the using of IGD,the detec- tion speed is increased and precision is improved.
