这是一个专门为菲涅尔衍射设计的一个仿真程序！参考光为平面波！本人测试过，没有问题存在！(This is a design specifically for the Fresnel diffraction of a simulation program! A plane wave reference beam! I tested, no problem!)

运用偏微分方程(PDE)方法进行图像处理的matlab程序，包括图像滤波、图像分割、插值、图像增强、恢复及一些方程组求解等在偏微分方法处理图像处理领域常用且重要的处理程序，供大家学习。(The use of partial differential equations methods matlab image processing procedures, including image filtering, image segmentation, interpolation, image enhancement, restoration, and some partial differential equations approach to solving such as in the field of image processing procedures used and important for them to learn.)

这写程序是对加水印之后图像的攻击，包括加噪声，各种滤波，剪切，压缩攻击和旋转等。(This writing process is a plus watermark image after the attacks, including the increase in noise, various filtering, shear, compression and rotation attacks.)

极化SAR图像中的将协方差矩阵数据进行PAULI分解的程序(Polarization SAR images will covariance matrix data Pauli decomposition process)

国外的一个车牌识别程序，主要是基于颜色特征提取分割的，内置神经网络。(A license plate recognition program abroad, mainly segmentation based on color feature extraction, built-in neural networks.)

运动模糊图像的去模糊算法（盲反卷积），里面有.exe文件(Motion blurred image to fuzzy (blind deconvolution)

这是基于稀疏表示的图像重建，用来做图像去模糊或超分辨，绝对可以用(Sparse Representation for Image Restoration)

说明：  计算两个离散变量x和y的联合熵z = H（x，y）。 输入：x，y：两个相同长度的整数向量输出：z：联合熵 可以使用，有利于学习目的(Compute joint entropy z=H(x,y) of two discrete variables x and y. Input: of x, y: two integer vector of the same length Output: z: joint entropy good for learning purposes)

DCT域图像水印算法，并根据携密载体提取秘密信息(DCT domain image watermarking algorithm, and extract secret information according to the carrier.)

说明：  用opencv编写的视频捕捉以及边缘提取的程序，调试成功，另附调试用的avi视频，希望对大家有所帮助(Opencv prepared with video capture as well as the procedures for edge detection, debugging success, followed by the avi debug video, hope to help everyone)
