iris recognition using haar wavelet

说明：  基于人眼视觉模型的双正交小波变换算法，通过实验验证,该算法在对嵌入水印后的图像进行有损压缩、剪切、污染、添加各种噪声等处理后,提取出的水印仍表现出了较好的鲁棒性。(Human visual model based on biorthogonal wavelet transform algorithm, experiments show that the algorithm of the watermarked image lossy compression, shear, pollution, after adding all kinds of noise, the performance of the extracted watermark is still a good robustness.)

说明：  是基于MATLAB软件编的小程序。该程序是K均值算法，应用于模式识别中(K-mean algorithm)

是用主元分析法实现的较高识别率的人脸识别，开发环境是MATLAB(It is the principal component analysis method is used to implement the high recognition rate of face recognition, development is the MATLAB environment )

I forgot the name of codes

这是自己写的实现哈夫曼编码的几个MATLAB程序，可以直接运行(This is the realization of their own to write several MATLAB programs Huffman coding, can run)
