使用matlab实现zernike模板系数的求解，避免了人工计算的麻烦与复杂(Using matlab to achieve the solution of coefficient zernike template to avoid the trouble of manual calculation and the complexity of)

运用lssvm的分类用法，详细描述了每一部分的意义(Classification of LSSVM)

This is matlab simulation source code for ASP digital communication system.

分组法求点方向图.若要求其他的指纹图像的点方向图,将“fp=imread( finger.tif ) 读入指纹图象”里的imread的参数修改成所需要的图像文件名。图像准备好后，在matlab中直接运行即可。(Packet Method pattern requires fingerprint image point pattern, fp = imread (' finger.tif to' ) reads the fingerprint image " the imread parameters modify the image files into the required names. The image is ready, you can run directly in matlab.)

说明：  检验已有的一组数据的概率分布是否为某种分布(Verify whether the data is a certain distribution)

说明：  提取图片的纹理特征，灰度共生矩阵包括四个方向的熵，对比度等特征以及对用的均值和方差，共80维特征向量(Extract the texture features)

用乘同余法产生随机数 ,产生的(0-1)均匀分布的随机序列 白噪声产生程序,用乘同余法产生(Produced by the same method with more than random number generated (0-1) uniformly distributed random sequence white noise generation process, with the method generated by congruence)

这个matlab程序可以同时对图像做高斯滤波和中值滤波处理。(The matlab program can do Gaussian image filtering and median filtering.)
