| 摘 要： | 拐点特征是模式识别中经常用到的一类不变量．本文利用Ｈｏｕｇｈ变换找出图像轮廓中的直线段，确定其直线方程，将相邻两直线段延长相交得到的交点定义为拐点．由于Ｈｏｕｇｈ变换是统计平均的结果，所以求得的拐点较为稳固，抗噪声性能较好．文中也给出了拐点的具体算法．

| Abstract: | Invariant corner features are often used in pattern recognition. By using Hough transform, the lines in the image and their parameters can be steadily determined. Corner defined as the intersect of two neighboring lines then can be obtained more accurately and with unsensitive to noise. An algorithm to calculate the locations of conners is also gaven in this paper. |
