虹膜数据算法MATLAB

简明卡尔曼滤波介绍，适用于初学者，很容易理解。(Kalman filter concise introduction for beginners, it is easier to understand.)

matlab优化程序的使用(matlab optimize the use of procedures)

此程序可以解决pca问题，开发环境是matlab，希望对大家有帮助(This program can solve the problem pca, development environment is matlab, hope to help)

用Shepard方法实现散乱数据的曲面拟合(Shepard method using surface fitting of scattered data)

说明：  车牌识别是目前应用最广泛的识别技术之一大多数是用 Matlab 开发程序 (License plate identification Matlab development program)

说明：  谱减算法的MATLAB实现程序，附带带噪语音文件。wavread一行可以改成自己需要的语音文件和噪声文件，可以查看输入和输出信噪比(MATLAB spectral subtraction algorithm implementation process, with noisy speech files. wavread line can be changed to their needs and noise files voice files, you can view the input and output signal to noise ratio)

针对双极性、单极性码产生直扩系统，并加上宽带噪声干扰，(For bipolar, unipolar codes have a direct expansion system, and with broadband noise,)

pca 主成分分析的matlab代码。主成分分析（Principal Component Analysis，PCA）， 是一种统计方法。通过正交变换将一组可能存在相关性的变量转换为一组线性不相关的变量，转换后的这组变量叫主成分。(PCA principal component analysis matlab code. Principal component analysis (Principal Component, Analysis, PCA) is a statistical method. Through orthogonal transform a group may be related to variable conversion is not related to a set of linear variables, this set of variables called principal component transformation.)

说明：  计算lzernike矩，用于图像的额模板匹配或者别的方向(zernike:Calculate lzernike moments for image frontal template matching or other directions)
