压缩感知程序

Jpeg图像压缩的Matlab源码，供研究Jpeg图像压缩的朋友参考使用。(Jpeg image compression Matlab source for the study Jpeg image compression friends use and reference.)

说明：  在IDL中将.nc格式的数据读取并绘图，文件夹中附有示例数据。(Reading and drawing data in.Nc format in IDL)

目的是改善影像质量，包括去除高频噪声与干扰，及影像边缘增强、线性增强以及去模糊等。分为低通滤波（平滑化）、高通滤波（锐化）和带通滤波。(The purpose is to improve the image quality, including the removal of high frequency noise and interference, and image edge enhancement, linear enhancement and deblurring. Into a low-pass filter (smoothing), high-pass filtering (sharpening) and bandpass filtering.)

图像增强的算法，但是有一定的局限性……但是对于一般比较典型的问题效果还是不错的……(Image enhancement algorithms, but there are some limitations ... but for a typical effect is good ...)

统计图像中某区域在整个图像中所占的百分比.(comput the percentage of the gived area in the whole image)

对采样得到的180幅断层图像进行重建，并针对其中的一幅图像进行处理，并且统计图像中颗粒的大小和数目！(Tomographic images of 180 samples obtained were rebuilt, and for which an image processing and image size and number of particles statistics!)

说明：  图像融合算法，高通滤波法、IHS法、PCA主成分分析、小波融合、小波和IHS结合的融合方法(Image fusion algorithm, high pass filter method, IHS method, PCA principal component analysis, wavelet fusion, wavelet and IHS fusion method)

实现地震资料的多次波处理,实现相同点的叠加，进而切除(to complish the goal that the noise can be suppressed in the seismic data)

matlab 写的提取图像亚像素边界的程序，和Canny算子有比较，里面有两张示例图像！(matlab write the image to extract sub-pixel border procedures, and the Canny operator have more, there are two examples of images!)

利用contourlet变换、小波变换等方法，进行图像去噪，经过调试，完全可以运行，效果不错(Contourlet transform, wavelet transform methods for image denoising, debugging, can run, good results)
