信号压缩传感的实现(正交匹配追踪法Orthogonal Matching Pursuit)(The realization of signal compression sensing)

图象特征的边缘轮廓提取算法，对初学者很有帮助。(characteristics of the image edge contour extraction algorithm, useful for beginners.)

有色噪声干扰非平稳状态下，MVDR扩展凹槽滤波形成方法(With colored noise under non-steady state, the the MVDR extended groove filter forming method)

说明：  实现 %1、利用RGB模型识别天空区域；2、利用边缘识别检测天空边缘分割线；3、利用预测边缘点和实际边缘点的周围区域的均值滤波与本边缘点下方的像素之间的差异大小来修正天空边缘分割线 %4、将sky_seg+depthmap_v2中多余的带注释的地方删掉了 %！！！记得在295行，一定要改动是用I6还是I7，如果用sky_initia(f = edge(double(BW),'canny',thresh,sigma);)

彩条产生程序。。。。720p需添加74.25M时钟(colorbar generation. need 74.25mhz clock if 720p gen)

基于小波包变换的去噪处理 全局阈值去噪图像 对图像进行平滑处理以增强去噪效果（中值滤波）(Denoising based on wavelet packet transform global threshold denoising image smoothing image enhancement and denoising effect (median filtering))

包含二维广义S变换程序和测试程序，用于对图像进行时频分析。matlab版本R2011b,操作系统为32位win7。在2G内存下最大只能对84*84的图像进行处理，更大的图像会出现out of memory的问题。目前网上还没有这个程序，包括本站，pudn，ilovematlab都没有。把程序上传到这三个地方，望大家一起来改进它。(Contains a two-dimensional generalized S transform procedure and testing procedure.It is used for the time-frequency analysis of images.Matlab version :R2011b, operating system: 32 win7. Tests under 2G memory can only process 84* 84 images.A larger image will incur "out of memory" problems. This program is not found online before, including this site, CSDN, ilovematlab. Upload the program to the above three websites, hoping it improved by the help of everyone.)

说明：  本程序利用python程序对hdf文件进行处理，转换格式。(This procedure USES python program to process THE HDF file, convert the format)

自己编写的图像腐蚀与膨胀matlab代码，经试验证明与matlab中自带的腐蚀和膨胀函数运行效果相同，可供初学图像处理的同学参考使用。(The image corrosion and expansion matlab code written by myself has been proved to be the same as the corrosion and expansion function of the matlab. It can be used by students who are ready for beginner image processing.)

可以动态调节运行环境的参数，重要参数的提取，利用自然梯度算法。( Can dynamically adjust the parameters of the operating environment, Extract important parameters, Use of natural gradient algorithm.)
