Detecting Circles Using a Two-Stage Approach被引量：1
《Journal of Electronic Science and Technology》2014年第3期318-321,共4页Wen-Yen Wu 
supported by the I-Shou University under Grant No.ISU 102-05-01
We propose a two-stage method for detecting circular objects in this paper. In the first stage, curves are divided as linear segments or nonlinear segments. A least square estimator is used to find the estimated cente...
