MatlabTutorial-6-5

很好的小波应用实例文档，介总结内容有小波用于去噪、图像压缩、边界扭曲、图像融合、小波包的分解和重构等等，附详细的MAMTLAB代码(Application of wavelet good document, refer to summarize the contents of wavelet denoising, image compression, border distortions, image fusion, wavelet packet decomposition and reconstruction, etc., with detailed MAMTLAB code)

You can use this script to generate synthetic DWMRI or DTI datasets

说明：  基于matlab颜色特征图像检索的颜色特征的提取(Matlab color feature based on the color image retrieval feature extraction)

Linear Spatial Pyramid Matching Using Sparse Coding for Image Classification

一种新型的改进的lcmv算法,实现了波束的形成，相比较很多算法有了改进(A new improved LCMV algorithm)

说明：  拉丁超立方采样包括还有约束和没有约束的两种。(Latin hypercube sampling includes both constrained and unconstrained sampling.)

信号时频分析，小波变换，加窗（汉明窗，矩形窗，布莱克曼窗）(Time-frequency analysis, wavelet transform, windowed (Hamming window, rectangular window, Blackman window))

这个程序基于matlab，用经典的算法用于求解方腔流问题(This program is based on MATLAB classic algorithm for solving the cavity flow problem)

By using this matcode codes a simple frequency Hopping system can be simulated. The number of frequencies to be used can be changed by changing the parameters
