图像加密 matlab程序 图像加密的程序 混沌系统图像加密的程序(encrypt photo)

基于DCT,DWT,SVD的图像鲁棒水印算法，并在GUI界面展示(Image watermark algorithm based on DCT, DWT, SVD and displayed on GUI interface.)

一个阈值去噪程序，包括经典的去噪方法，如折中阈值，自适应阈值等等。(A threshold denoising procedures, including the classical denoising methods, such as compromise threshold, adaptive threshold and so on.)

说明：  进行三维去高后，根据sar参数信息，将斜距转变为地距。(After performing three-dimensional height removal, the slope distance is converted to ground distance according to the sar parameter information.)

自己编写图像旋转； （1）可以任意设定旋转中心； （2）旋转通过坐标矩阵和旋转矩阵一步到位，得出旋转之后的对于坐标矩阵；（myrotate和myrotate1功能一样，后者只是在前者基础上，将旋转矩阵和平移矩阵集成到一起了）； （3）自带构造测试矩阵，可以直接运行；(rotate img by myself all center )

说明：  用matlab写的分水岭算法用于图像分割写的不是很好有需要的看看吧(using Matlab was a watershed for image segmentation algorithm was not very good in need and let's see it)

说明：  本程序基于Matlab,初步实现图像增强的基本操作,实现 图像明暗度调整， 图像旋转，更改颜色显示方式，直接灰度调整，图像求反，动态范围压缩，显示原始图像直方图，直方图均衡化，滤波增强等功能(This procedure based on Matlab, the initial realization of the basic operation of image enhancement, image brightness adjustment, image rotation, change the color display, direct gray-scale adjustment, for anti-image, dynamic range compression, display the original image histogram, histogram equalization , enhanced features such as filtering)

说明：  MTLAB编写的程序，包括形态学梯度检测二值图像的边缘、用水线阈值法分割图像等。(MTLAB preparation procedures, including detection of morphological gradient binary image of the edge of the water line thresholding segmentation images.)

能够提取一幅图片的不变矩特征值，方便大家学习图像识别方面的开发技术(Able to extract a picture of the moment invariant features of value, to facilitate learning in the development of image recognition technology)
