.Fast detection of multi-circle with randomized Hough transform[J].Optoelectronics Letters,2009,5(5):397-400 Fast detection of multi-circle with randomized Hough transform 蒋联源 Department;Computer;Engineering;Guangxi;University;Technology; Abstract:       Randomized Hough transform (RHT) is an effective method for circle detection. But when dealing with multi-circle complex images,the random sampling will bring lots of invalid accumulations and result in a large number of calculations. In this paper,by selecting three points of the candidate circle,a fast detection algorithm of multi-circle with randomized Hough transform is presented. Experimental results demonstrate that the proposed scheme can quickly detect multiple circles,and has a strong robustness. Hits: 3578 Download times: 207 View Full Text    Download reader
