使用LSB算法将信息图像嵌入到另一个载体图像中！-LSB algorithm using the information image is embedded into another vector image!

JSteg隐写技术matlab实现代码--基本思想：用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位，但若量化后DCT系数为0或者1，则不进行处理。（DCT系数的LSB嵌入） -JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the leas

基于matlab的简单人脸识别，这里通过对人脸图像打上网格，对区域块图像做二值分析，通过像素比例来做处理。进而得到人脸区域。-A simple matlab based face recognition, the face image of a grid, the two value image through the analysis of the regional block, the proportion of pixels to process. To get the face reg
