这里是几篇关于语音增强中有声无声估计的VAD算法的文献，希望和大家一起讨论，做出与之相关的matlab源代码。(Here are a few on the speech enhancement in a silent voice has estimated VAD algorithm literature, hope and everyone together to discuss and make related matlab source code.)

PCA Based implementation souce code

使用matlab仿真hitran，用以计算气体吸收系数计算(Use matlab simulation hitran, to calculate gas absorption coefficient calculation)

说明：  基于DWT的图像压缩，上数字图像处理可的大作业(DWT Compression)

这是很有效的无约束共轭梯度法和牛顿法,愿和大家分享!(This is a very efficient unconstrained conjugate gradient method and Newton method, is willing to share!)

feature selection based on pearson coffeicients

这个也是关于空间谱的matlab 挺好的 可以(This is on the spatial spectrum of matlab can be quite good)

randgen(mu,mu1,mu2,cov1,cov2,cov3) = Random generation of Gaussian Samples in d-dimensions where d = 2 mu, mu1, mu2 = (x,y) coordinates(means) that the gaussian samples are centered around cov1, cov2, cov3 are the covariance matrices and will vary changing the shape of the distribution, example: cov = sigma^2*Identity Matrix, where sigma^2 = a scalar N = the number of gaussian samples used are provided as user input, A test set of N/2 and a training set of N/2 gaussian samples is also generated Output is directed to the command window and a plot of the distributions are generated

avo_abe - AVO intercept and gradient attributes for P-P and P-S

说明：  this is a code for mesh and cracking body
