Include: digital image data display matrix and its Fourier transform two-dimensional discrete cosine transform image compression method using gray-scale transformation of the contrast-enhanced images using two-dimensional median filter function by medfilt2 of salt and pepper noise image filtering using MATLAB The function affected by noise interference filter2 images mean filter Adaptive Image Filtering Wehner use five kinds of different gradient method to enhance image sharpening images of high-pass filtering and mask treatment using Butterworth (Butterworth) low pass filter noise by smoothing the images deal with the use of Butterworth (Butterworth) high-pass filter for sharpening images treatment)

视频压缩感知系统的基追踪算法仿真，可以运行通(Video compress and sensing system that based on BP.)

功能还算完善，可能最后调试有小的问题，但是功能模块基本实现(just do it)

说明：  一种加核的PCA算法，比PCA算法识别率高很多，所加的核可以用于其他算法。(An increase in the PCA algorithm for nuclear than the PCA algorithm is much higher recognition rate, the increase of other algorithms can be used for nuclear.)
