A Rapid Detection for RHT Multi-circle Objects Based on Edge Feature Points' Cluster Analysis

An improved and rapid arithmetic for multi-circle detection using randomized hough transformation(RHT) based on edge points' cluster analysis,is put forward.The result shows that this method can rapidly and accurately extract multi-circle objects on complex images,which has tremendous value in use especially when the objects are separate and own larger shape.Meanwhile,this arithmetic has a better ability of resisting noises.
