利用matlab的DCT2函数，对图像做变换并压缩。并用8*8对图像分块，对每一块计算均方值作为阈值。(DCT2 use the matlab function, and transform the image so compressed. And 8* 8 image block, a calculation of each mean square value as a threshold.)

非压缩视频图像帧内水印的密写与复密写研究，源码和论文材料(Video Watermarking Steganography)

说明：  给出数字图像处理的，程序MATLAB的原代码，可以直接用于实验与验证(Given digital image processing, the original code of MATLAB program, can be directly used for experiment and verification)

关于在图形图像处理过程中纹理特征提取方法的介绍(About in the process of image processing texture feature extraction method is introduced)

这是我们非线性课程的一次作业，有分岔图，蛛网图，庞加莱截面，希望对大家有用。(This is our first non-linear operation of the curriculum, there is bifurcation diagram, spider diagram, Poincare section, in the hope that useful to everyone.)

SAR影像cloude分解，提取极化信息(PolSAR cloude decomposition)

双目摄像机标定程序，给出摄像机内外参数，并完成三维立体重建。(Binocular camera calibration procedures, given internal and external camera parameters, and complete the three-dimensional reconstruction.)

运用微粒群算法PSO 来进行图像的边缘模板匹配 的matlab程序 函数说明见doc文件(PSO for image template matching)

DensePose用深度学习把2D图像坐标映射到3D人体表面上，再加上以每秒多帧的速度处理密集坐标，最后实现动态人物的精确定位和姿态估计。该技术集目标检测、姿态估计、目标部分/实例分割等多种计算机视觉任务于一身的一个综合问题。(DensePost maps 2D image coordinates to 3D human body surface by in-depth learning, and processes dense coordinates at the speed of multiple frames per second. Finally, it realizes precise positioning and attitude estimation of dynamic characters. This technology integrates many kinds of computer vision tasks, such as target detection, attitude estimation, target part/instance segmentation, etc.)
