The Application of Grads Hough Transformation in Circle Detection
Lan Gan · Journal of East China Jiaotong University · 2007
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.
