Coloring-Problem

基于MRF模型的变化检测算法仿真 MRF建模用于SAR去噪，再通过EM算法实现变化检测(MRF model-based change detection algorithm simulation)

matlab实现gamma校正的算法，用以调整光照不均的图像。(matlab to achieve gamma correction algorithm to adjust the uneven illumination of the image.)

说明：  小波变化是对傅里叶变换和短时傅里叶变换的一个突破，其改变就在于，将无限长的三角函数基换成了有限长的会衰减的小波。(Wavelet transform is a breakthrough of Fourier transform and short-time Fourier transform. Its change lies in that the infinite trigonometric function base is replaced by the finite attenuation wavelet.)

说明：  计算GIF彩色图像的差异，两幅图像大小一致且调色板一致。其中Psnr 为两幅图像的psnr值.P 为两幅图像之间像素索引不同的索引值占图像大小的比例。(GIF image color difference calculation, the two images the same size and same color palette. One Psnr the two images psnr value. P index for the pixels between two images, the index values of different ratio of total image size.)

说明：  本程序是用来做图像编码的，主要采用的算术编码的思想(This procedure is used for image coding, the main idea used in arithmetic coding)

DMD相机原理，单像素成像原理，压缩感知(The principle of DMD camera)

基于EM-马尔科夫随机场-ICM的图像分割程序，很好的学习代码(EM-based Markov random-ICM image segmentation procedures, good learning code)

NSCT的分解与重构，用于图像处理，里面为非下采样轮廓波的工具箱(NSCT decomposition and reconstruction for image processing, which is a toolkit for subsampled contourlet)

说明：  基于harris角点特征的图像配准程序 matlab实现(Harris corner on the characteristics of matlab image registration process to achieve)

CS压缩传感的初级教学代码，使用OMP重构，已注释，包括1维信号，2维图像的重构，分别使用dct和小波稀疏，列扫描和分块法进行omp重构(CS compressed sensing primary teaching code using OMP remodeling, already commented, including a 1-dimensional signals, 2-dimensional image reconstruction, respectively, using the DCT and wavelet sparse column scanning and sub-block method omp Reconstruction)
