课程作业，可视密码的matlab实现代码以及展示用ppt(Course work, visual cryptography matlab code and display ppt)

说明：  实现手机拍摄图像的二维码图像的提取，包括QR码的旋转与校正，也可以用于其他条码，但是效果不是很好(The realization of mobile dimensional code image captured image extraction, rotation and including a QR code correction can also be used for other bar code, but the effect is not very good)

光流法实时实现的文献及代码，2012发表于cvpr，200*200的图像，每秒可达200帧，2012_CVPR_Lip-motion events analysis and lip segmentation using optical flow(Optical flow method to achieve real-time literature and code, 2012 published in cvpr, 200* 200 images per second, up to 200, 2012_CVPR_Lip-motion events analysis and lip segmentation using optical flow)

对图像进行平滑去噪，提高图像的质量，为后期的图像处理打基础(very good)

基于openCV的gabor函数,一位牛人编写的。希望对大家有用(gabor function based on openCV)

基于互信息的图像配准算法，优化算法采用Powell和粒子群向结合的算法(Based on mutual information image registration algorithm, using Powell optimization algorithm and particle swarm algorithm to combine)

很详细的Harris算法讲解~~~包括非最大值抑制的算法~自适应~~(Harris algorithm is very detailed explanation ~ ~ ~ including non-maximum suppression algorithm ~)

采集RGB-D深度图像生成点云矩阵，属于RGB-D SLAM的前端处理过程(Collecting depth image to generate point cloud)

基于NCC与SSDA的快速特征点匹配融合算法（图像匹配）(NCC and the SSDA-based feature points matching the rapid integration algorithm (matching))

数字图象处理，模式识别，人脸识别，包括了程序和一个人脸库，是相当好的学习东西(Digital image processing, pattern recognition, face recognition, including the procedures and a face database is very good to learn things)
