基于Hough 变换的圆检测方法
首发时间:2006-11-13
摘要:总结了圆检测的常用方法。提出了一种改进的Hough变换用于圆检测,该方法先对图像进行预处理,然后进行变换,主要思想是用多维数组来代替经典的循环过程。通过对经典Hough变换的改进,提高了检测速度。

Circle Detection Using Hough Transform
Abstract:Some methods of circle detection are summarized. And an improved Hough transform of circle detection is proposed to preprocess the image first and process the Hough transform. Its main idea is to replace the circulation with multidimensional array. The improved Hough transform increase the performance of circle detection.
Keywords: Circle detection Classical Hough transforms Randomized Hough transform
