梯度Hough变换在圆检测中的应用
The Application of Grads Hough Transformation in Circle Detection
【摘要】 介绍了一种有效的利用图像梯度信息的Hough变换方法——梯度Hough变换(GHT).详细讨论了梯度的求取、GHT的详细算法,讨论了GHT算法和直接累加Hough变换算法的区别及改进之处.
【Abstract】 One kind of efficient Hough Transformation(HT),which uses the grads information of image-Grads Hough Transformation(GHT),is introduced in this article.The method of computing grads and detailed algorithm of GHT are given out.Finally,the connection and discrimination between GHT and DHT(Direct HT) are discussed.
