数字图像处理matlab版 冈萨雷斯 一书中的附加源程序，生成的M文件，直接可用 (Digital image processing matlab version Gonzalez one additional source book, M-generated documents, directly available)

说明：  KM算法，通过对图片的像素点特征分类，实现图片杂质检测等功能(KM algorithm, through the image of the pixel classification to achieve image impurity detection and other functions)

sift角点检测及匹配，在不同尺度空间下的角点检测方法，很方便实用。(sift corner detection and matching, the corner detection methods under different scales of space, it is convenient and practical.)

sift算法的核心，siftWin32.exe的源程序，可执行，可导入Matlab(The core of the SIFT algorithm, the source of siftWin32.exe, executable, can be imported to Matlab)

基于LSB的隐写算法，以及基于猫脸变换的图像隐写改进算法。(The steganography algorithm based on LSB and the image steganography based on cat face transform.)

随机森林用于 图像处理matalab 代码(Random Forest matalab code for image processing)

本算法先将彩色图像变换成灰度图像，在进行基于区域生长法进行图像分割(It segmented image with region growing. Then local adaptation luminance was computed via region-based bilateral filter. It outputted low dynamic range images in conjunction with tone mapping operator. )
