介绍fft指纹增强算法，该源码测试可行。希望对大家有用。-Introduction fft fingerprint enhancement algorithm, the source test feasible. Hope useful for all of us.

这个是基于php下的指纹算法，其中包括指纹算法的训练。-This is based on PHP fingerprint algorithm, including the training of fingerprint algorithm.

libsvm相似性算法测试例子,可以用于人脸,指纹,验证码识别时的调用,本人自己写的-libsvm similarity algorithm test example, can be used for face, fingerprint verification code identification when calling, I wrote it myself
