In feature matching , a dot pattern matching method is developed , which combine subschema matching method for solving rotations and scale changes problems , and employ variable bounding box to solve translations problem . then the problems of arbitrary translations , rotations , and scale changes in feature matching have been well 特征匹配算法采用了基于点模式的匹配方法,并结合基于结构的匹配方法解决图像的旋转、平移问题,同时采用可变限界盒方法解决图像的变形问题,使得指纹图像匹配中因图像旋转、平移、形变等带来的问题得到了较好的解决。
