：数字水印将感觉不到的信号嵌入到声频、视频和图像中以实现不同的目的。例如: 添加标题和版权保护。首先介绍 了有关数字水印的基本原理、重要属性及其主体框架。然后,将数字水印按不同角度划分为不同种类。讨论了各种各样的数 字水印算法以及数字水印在不同领域的应用,并简要介绍了对数字水印的攻击。最后,给出了数字水印当前的研究现状和发 展形式及前景。(: Digital watermark embedding imperceptible signals to the audio, video and images to achieve different purposes. Example: Add a title and copyright protection. Firstly, the basic principle about digital watermarking, and the main framework of the important attributes. Then, the digital watermark according to different angles into different types. Discussed a wide range of digital watermarking algorithms and digital watermarking applications in different fields, and a brief introduction of the digital watermarking attacks. Finally, the digital watermark of the current situation and development in the form of research and prospects.)

说明：  一个基于块的纹理合成matlab源码程序(A block-based texture synthesis matlab source program)

在图像处理中实现带通滤波器的功能的matlab实现代码(Bandpass filter)

图像处理中最常用的各种国际标准测试图像，包括Lena、Barbara、Cameraman、Peppers等图片的多种格式。(The most commonly used in image processing in various international standard test images, including Lena, Barbara, Cameraman, Peppers, and other images in multiple formats.)

为图像添加各种噪声，如高斯噪声、泊松噪声、椒盐噪声等。（需有openCV）(Add all kinds of noise for the image, such as Gaussian noise, Poisson noise, salt and pepper noise. (The need for openCV))

总变分法TV模型代码domo，部分代码，对图像恢复，去噪有一定作用(Variational method of total TV model code domo, some code, for image restoration, denoising have a certain role)

说明：  “求RGB转HSI空间小程序.m”为主函数调用rgb2hsi.m，由于matlab没有自带这个函数，所以自编了一个，用于进行阴影去除。( Seeking RGB to HSI space program. M the main function call rgb2hsi.m, as a result of matlab does not own this function, so a self-compiled, used for shadow removal.)

说明：  一款实用的滤波器设计软件，有助于自行设计滤波器时作参考 (A practical filter design software, will help to design filters for reference)

变分偏微分方程图像处理工具包，包括计算曲率，方差，L1,L2范数等29个实用算法(variational PDE image processing tool kit, including the calculation of curvature, variance, L1, L2 norm, and other practical algorithms 29)

主要用于织物图像处理中，织物起球图像的频域纹理滤除，将图像从空间域变换到频率域。(Mainly used in fabric image processing, the fabric pilling texture image in the frequency domain filter, transform the image from space domain to the frequency domain.)
