In the matching section, a reference point orientation algorithm based on block direction and its sine component is given at first. The method finds the singular points according to their neighbor area characters, and then orients the reference point.
在指纹匹配部分,本文提出了基于块方向及其正弦分量的参考点定位算法和基于结构特征的分段式指纹匹配算法。
