【摘要】 对直线标准 ＨＯＵＧＨ变换 （ＨＴ）和改进的直线 ＨＴ两种算法的映射策略和时、空指标进行了分析。在此基础上提出了一种采用“多对一”策略的圆检测ＨＴ新算法，与圆检测的标准算法比较，该算法有更好的时空指标，实验结果证明了新算法的有效性。更多还原

【Abstract】 The map strategy and performance between the conventional Hough Transformation (HT) and modified HT algorithm for strait line are analyzed.Based on the analyzing,a new HT algorithm of circle detect is proposed which adapts the“many to one”strategy and has better performance than conventional HT of circle.更多还原
