matlab 时频分析工具箱， 对于做时频联合分析很有用(time-frequency analysis matlab toolbox for doing time-frequency analysis is useful)

用matlab实现算数编码、哈弗曼编码以及LZW编码（能够区分大小写和数字进行编码）含测试文本和结果(Using matlab realize arithmetic coding, Huffman coding and LZW coding (case-sensitive and numbers can be encoded) containing test text and results)

张正友相机标定程序 张正友摄像机标定法是一种简单实用的标定法，本次试验中共取用了同一摄像机从不同角度拍摄的六幅图像，经过Harris角点提取并优化从每幅图像中取十个特征点来进行摄像机标定（这十个点的世界坐标相同）。(Zhang Zhengyou camera calibration procedure Zhang Zhengyou camera calibration method is a simple and practical calibration method, this test CCP access to the six images of the same camera taken different angles, through Harris corner extraction and optimization take ten each image camera calibration feature points (the same world coordinate these ten points).)

optimization of many codes programming in matlab

对声音中嵌入的图像进行提取，此图像时矩阵排列(Embedded in the sound image was extracted from a matrix of this image)

fit_mix_2D_gaussian - fit parameters for a 2D mixed-gaussian distribution using EM algorithm format: [u,covar,t,iter] = fit_mix_2D_gaussian( X,M ) input: X - input samples, Nx2 vector M - number of gaussians which are assumed to compose the distribution output: u - fitted mean for each gaussian (each mean is a 2x1 vector) covar - fitted covariance for each gaussian. this is a 2x2xM matrix. t - probability of each gaussian in the complete distribution iter - number of iterations done by the function
