摘要： 针对指纹图像方向性强的特点,构造了方向加权模板,在对文献[4]提到的二值化方法作一定改进的基础上提出了一套有效的预处理方法,实验结果证明,该套算法处理效果好、速度快,有较高的使用价值。

关键词: 方向性, 加权, 模板

Abstract: This article constructs the directional weight module, and presents an effective method by modifying the binary algorithm used in the reference [4]. The result of experiments show that the method has the advantages of good processing effect, fast operating speed and high value in practicing.
