%基于DCT的水印算法
%数字水印处理系统主要由水印嵌入和水印检测两个过程。
%水印嵌入过程为:数字水印(X)、原图像(I)和密钥/公钥(K)通过数字水印嵌入算法形成嵌入水印后的图像(I*)。
%水印检测过程为:数字水印(X)、水印图像(I*)和密钥/公钥(K)通过数字水印检测算法检测出数字水印或有无水印。
%基于DCT变换的水印算法:将一个随机序列作为水印信号嵌入到图像DCT变换重要分量的幅度成分中(幅值较大的n个系数作为重要分量)。
%定义一个相似函数来检验水印提取是否成功。试验结果表明,该算法具有不可见性,对通常的图像处理,如剪切、缩放、中值滤波、压缩等
%以及噪声干扰都具有一定的鲁棒性。(err)

gbvs
静态图像显著性分析程序,利用matlab开发。加州理工三位教授所写。(Software] Saliency Map Algorithm : MATLAB Source Code
Below is MATLAB code which computes a salience/saliency map for an image or image sequence/video (either Graph-Based Visual Saliency (GBVS) or the standard Itti, Koch, Niebur PAMI 1998 saliency map). See the included readme file for details. I also have a newer, simpler version implementing only the Itti algorithm (see simpsal/readme.txt).
Please try it out and email me if you have any questions.
Download:
Please select one of the following to download:
[gbvs.zip]
This package includes an implementation of the full GBVS algorithm. It also lets you compute an Itti, Koch, Niebur saliency map. It includes a function for computing the ROC score between eye-movements (provided as x,y fixation points) and a saliency map, and a function for displaying a saliency map overlayed on top of an image (as in the screenshot below).
Right after you download the zip file, you must change into the gbvs/ directory and run:

DcmtkTest
本程序使用dcmtk库,可以显示大部分的DICOM图像。非压缩、压缩黑白图像以766灰阶显示,彩色图像正常显示。
对于初用dcmtk库的开发者来说,入门较难,本程序已使用VC6工程将主要库加入工程中,可以参考本工程的设置。另外,对于高于8位的黑白图像,本程序也提供一个处理方法的参考。(This procedure used dcmtk library, you can see that the majority of the DICOM image. Non-compressed, compressed to 766 gray-scale black-and-white images show that color image display. Dcmtk library used for the early developers, the entry more difficult, the procedure has been in use for the main library VC6 project will join the project, can refer to the project settings. In addition, higher than the 8-bit black-and-white images, the program also provides a reference method.)
