| 摘 要： | 基于大量的实验提出了一套行之有效的指纹处理算法，主要包括使用基于方向图的自适应旋转滤波器、与自适应增强滤波同时进行的自适应阀值边缘处理、自适应阀值二值化，很好地增强了指纹图像的清晰度，同时起到了很好的滤波作用，为可靠、准确地实现指纹自动识别系统奠定了最可靠的基础．

| Abstract: | By lots of tests,we find a series of algorithms for fingerprint preprocessing,these algorithms are very effect,they are mainly composed of enhancing filter template which is based on the directional segmentation,local selfadaptive edges processing with filtering, local selfadaptive binarization,deleting false minutia pixel after thinning by these processing algorithms, the fingerprint images are enhanced very well and wipe off the disorder images of edges after the fingerprint images are thinned;these algorithms can enchance the fingerprint images and are the credibility basis of AFIS |

| Keywords: | fingerprint image directional image local selfadaptive disorder image of edges |
