一种主元分析的人脸识别matlab源码，利用SVD分解提取主分量进行人脸识别(A principal component analysis for face recognition matlab source code, the use of SVD decomposition to extract principal components for face recognition)

对位图图像利用JPEG标准进行正交变换、量化、扫描从而达到压缩，同时解压显示其压缩图像。(Bitmap image using JPEG standard orthogonal transformation, quantization, scanning to achieve the compression, and decompression display the compressed image.)

用rayleighchan 函数仿真时要注意最后要做相位补偿（此问题是导师发现的） 程序步骤： ~产生随机序列 ~产生瑞利信道 ~调制 ~记忆信道特征 ~信号通过信道 ~相位补偿 ~加高斯噪声 ~解调 ~计算仿真误比特率 ~计算理论误比特率 ~不同颜色画出误比特率曲线对比(Function Simulation with rayleighchan last thing to note when the phase compensation (this issue is found mentor) program steps: ~ ~ generated random sequence modulation in Rayleigh Road, ~ ~ ~ memory characteristics of the signal channel by channel ~ ~ plus Gaussian noise phase compensation ~ ~ demodulation bit error rate calculation simulation of bit error rate calculation theory ~ ~ different colors to draw curves of bit error rate)

本设计采用了一种基于三参数组合的方法对语音信号进行了清/浊音判决。在传统两参数（短时能量和过零率）算法基础上增加了自相关函数作为判决参数，减少了清/浊音信号误判率。(This design uses a combination of methods based on three parameters of the voice signals of the Qing/voiced sentence. In the traditional two parameters (short-term energy and zero crossing rate) algorithm based on the increase since the correlation function as a decision parameter, reducing the clearance/voiced signal false positives.)

用MATLAB来仿真FSK、PSK、DPSK的调制、解调过程，并通过实验来比较它们的误码率和信噪比的关系。内附有matlab源代码(Using MATLAB to simulate FSK, PSK, DPSK modulation, the demodulation process, and to compare their bit error rate and signal to noise ratio by the empirical relationship. Enclosed is the matlab source code)

this is texture classification

小波矩的matlab代码，主要用于全局特征提取使用，比较简便(Wavelet Moment matlab code, mainly for global feature extraction using relatively simple)

独立向量分析（IVA）是对独立成分分析（ICA）算法的一种扩展，将ICA中的单变量成分扩展为多维变量成分，可有效避免卷积盲源分离过程中的排序模糊性问题。(Independent vector analysis (IVA), a multivariate extension of independent component analysis, tackles the convolutedly mixed blind source separation (BSS) problem in a way to avoid the permutation problem by employing a multivariate source prior of the short-time Fourier transform (STFT) components. )

说明：  就是用MATLAB绘制,一个颜色编码的混淆矩阵。(MATLAB is used to draw a color coded confusion matrix.)
