信号进行EEMD分，作为希尔伯特黄变换的基础(try to decompose signal using EEMD，which as the Hilbert Huang Transtion basis)

介绍了混合高斯背景建模法提取运动目标的过程，自己写的，比较好理解，付视频一个，用自己的视频也可以(Describes the process of Gaussian mixture background modeling method to extract moving target, write your own, is better understood, paid a video, you can use your own videos)

说明：  图像稀疏编码的一种方法，可用于基于稀疏表示的图像压缩、去噪等(Sparse image coding method can be used for sparse representation-based image compression, denoising, etc.)

实现两幅bmp图像相减得到最终图像并显示(Realize two BMP image subtraction, get the final image and display)

用opencv实现对一幅图像的小波变换 opencv 图像二维小波变换(The wavelet transform of an image with opencv)

在计算鬼成像当中，用于生成计算散斑，有了计算散斑 可以做仿真或者其他用途(In the calculation of ghost imaging were used to calculate the generating speckle, speckle can do with computing simulation or other purposes)

积木效果显示图像

说明：  实现了图像与视频的信息隐藏，输入图片和视频可进行效果演示(The information hiding of image and video is realized)

小波图像去噪，全局阈值法，是多阈值小波去噪中两大部分：全局阈值法玉局部阈值法的重要组成部分。(Wavelet denoising, the global threshold method, the multi-threshold wavelet de-noising of two parts: the global threshold method jade local threshold an important part of the law.)

针对彩色图像的局部直方图均衡化，可以较好的增强图像细节(poshe,it can enhancements the detail of the image )
