| 摘 要： | 指纹图像预处理与特征提取是指纹识别的前提。提出一套基于方向滤波与模糊数学方法的指纹图像预处理算法，并给出了指纹特征提取及其后处理算法。指纹图像预处理首先求出指纹的方向场，然后根据方向场进行滤波，最后用模糊数学方法得到二值化图像。指纹特征提取则先从细化指纹图中得到特征点，并依据伪特征点的脊线与角度特征剔除伪特征点。

| Abstract: | Minutiae extraction and preprocessing algorithm is essential in fingerprint recognition. A preprocessing and minu tiae extraction algorithm is put forth with experiment result. The input Image is processed with directional filters and fuzzy bi narization. Minutiaes are extracted from thinned fingerprint image and false minutiaes are deleted by their characteristic. Ex periment show that it is effective. |
