Image-Compression

应用HHT与EOSA方法进行瞬时频率求解，生成边际谱(A program for instantaneous frequency )

此程序包含心音信号的低通滤波、小波去噪、EMD分解、希尔伯特黄变换以及心音阈值定位一系列算法。输入为采集到的单通道心音信号。入口程序为main.m (A program that process heart sound signals to separete each heart sound clearly.Functions like Low-pass filters and Hilbert transformers are involed.)

《matlab教程》配套光盘，很小，但含有众多源码，欢迎下载()

说明：  压缩传感介绍性文章，文章详细介绍了稀疏矩阵的构建方法(an introduction to compressed sensing and the sparse matrix)

现代信号处理大作业2-2，实现wv分布并画出3d图，指出了信号项和交叉项(2-2 large modern signal processing operations to achieve wv distribution and draw 3d map, pointing out items and cross-term signal)

用MATLAB 实现的综合云模型的实现。很有意思和参考价值(Implemented with the MATLAB implementation of comprehensive cloud model. Very interesting and valuable)

牛顿算法，用于求迭代方程的解，数值分析用(Newton algorithm for seeking solutions of iterative equations, numerical analysis using)

In histogram equalization we are trying to maximize the image contrast by applying a gray level transform which tries to flatten the resulting histogram. The gray level transform is a scaled version of the original image s cumulative histogram. That is, the graylevel transform T is given by T[i] = (G-1)c(i), where G is the number of gray levels and c(i) is the normalized cumulative histogram of the original image.

matlab粒子群程序，里面的bug请检查 (swarm)

这个程序是关于图像的方针，直方图方法； 画出直方图。(This program is about the principle of the image, histogram method draw histogram.)
