RSA加密

主要包括3种去噪方法，Bayesian Least Squares，BM3d 和Non-local means (this attachment contains three classical denoising methods Bayesian Least Squares，BM3d and Non-local means )

可直接计算得到多重分形谱,用于建立主成分分析模型，保证准确无误，是学习通信的好帮手。( It can be directly calculated multi-fractal spectrum, Principal component analysis model for establishing, Ensure accurate communication is learning a good helper.)

实现中值滤波的源程序 参数Hori是一个布尔变量，若为真，做水平中值滤波，否则，做竖直中值滤波。(achieve Median filtering of the source parameters Hori is a Boolean variable, if true, so the level of median filtering, otherwise, do vertical median filtering.)

说明：  使用MATLAB语言编写的非高斯噪声程序，通俗易懂，非常好用(Using the MATLAB language for non-Gaussian noise process, user-friendly, very easy to use)

使用盲数字水印实现DWT ，数字水印的嵌入和提取，小波变换(Using blind digital watermarking to implement DWT)

说明：  采用kalman滤波器进行目标跟踪的源代码(object tracking using kalman filter)

图像处理中C#畸变校正程序，针对鱼眼图像的径向畸变校正，利用空间直线在校正图像中仍然为直线的基本原理，且直线在除法模型下为圆弧，从而可以通过检测圆弧对鱼眼图像进行畸变校正。(Image processing program C# distortion correction for radial fisheye image distortion correction, the use of space in a straight line in the corrected image as the basic principle is still straight, and a straight line at the division model is a circular arc, so that the arc can be detected by fish eye image distortion correction.)

通过matlab自带函数等，实现复杂背景下，提目标外轮廓，并且去除内部小区域，得到边缘(By using MATLAB functions and so on, the target contour can be extracted under complex background, and the inner small area can be removed to get the edge.)

实现图像精确分割，基于ALpha Matting 的基础上的Sharedmatting图像分割算法(Accurate image segmentation,Sharedmatting image segmentation algorithm based on ALpha Matting)

图像复原，实现inverse Filter, Wiener Filter, Lucy-richardson 算法，里面包括PPT，代码和报告。非常有价值，是我视觉的大作业。(Image restoration to achieve inverse Filter, Wiener Filter, Lucy-richardson algorithms, which include the PPT, the code and reporting. Is very valuable, is my vision of the big job.)
