静脉指纹识别，实现了裁剪，图像预处理，特征提取，匹配等功能-Vein fingerprint recognition, to achieve a crop, image preprocessing, feature extraction, matching, etc.

指纹识别的matlab全代码，包括预处理，提取特征点，点匹配。。。其中用到gabor滤波-The whole fingerprint recognition matlab code, including preprocessing, feature point extraction, points matching. . . Which uses gabor filter

指纹图像基于小波变换的各种处理进行了分析、总结。图像处理包括基于小波变换的指纹图像滤波处理和基于小波的指纹图像增强处理。同时介绍指纹图像的预处理：目的是去除指纹图像中的噪音，将其转化为一幅清晰的点线图，便于提取正确的指纹特征。它分四步进行，即灰度滤波、二值化、二值去噪、细化。(The fingerprint image is analyzed and summed up based on the various processing of wavelet transform. Image pro
