• reference point orientation - 引用次数：5

  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。

  It has bad effect in bad image even that it can't locate the reference point. Futher reseach is need for better reference point location algorithm.

  因此参考点定位需要做进一步的研究,以求获得更好的定位算法。
