contrast

说明：  ROC曲线函数,横轴为虚警概率，纵轴为检测概率(ROC curve function, the horizontal axis is false alarm probability, and the vertical axis is detection probability)

一个光流算法的matlab源程序，在图像处理、前景检测与跟踪等方面有很多应用，推荐(An optical flow algorithm matlab source code in image processing, the prospects for detection and tracking, etc. There are many applications, the recommendation)

对张正友标定得程序重新详细标注了中文注释，方便初学者尽快入门，在最短的时间内了解程序流程，提高学习效率！(Zhang Zhengyou matlab calibration procedures, in order to facilitate a beginner, a code re-done every detail marked Chinese comments, so that we can understand the flow of the program as soon as possible!)

盲反卷积算法复原图像的代码,带注释,适合初学者学习(Blind image restoration code, with comments)

对图像添加各种噪声 高斯噪声 淑盐噪声(Add a variety of image noise, Gaussian noise, noise, salt-sook)

模拟闪变仪，用于检测电压波动与闪变，满足IEC推荐的平方检测法。(Analog Flickermeter for detecting a voltage fluctuation and flicker, meet IEC square detection method recommended.)

说明：  m-map工具箱，可以帮助画图，比如世界地图的背景(M-map toolbox, can help draw pictures, such as the background of the world map)

自己编写的关于2013年的文章 a variational method for multi-source remote-sensing image fusion 的程序，基本实现了相关功能。(I have written a progrma about a variational method for multi-source remote-sensing image fusion publish in 2013,and the basic functions of the problems have been solved.)

matlab实现的图像金字塔，过程很清晰，简单易学(matlab implementation of image pyramid, the process is very clear and easy to learn)

说明：  Jsteg_Mu可批量对JPEG图像进行Jsteg隐写。 Jpeg_Or 为jpeg密写的原始图像的文件夹， Jpeg_Di 为jpeg密写后密写了的图像的文件夹,code_file 为密写的文件,rate 为密写嵌入率.(Jsteg_Mu JPEG images can be batch Jsteg on steganography. Jpeg_Or jpeg steganography for the original image folder, Jpeg_Di as jpeg steganography written after the close of the images folder, code_file written document for the dense, rate for the steganography embedding rate.)
