matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过，如未修改，可提取隐藏信息。当有修改发生时，可以定位修改的位置，并在图上标出。标识面积占修改面积的75％，一般修改都能标出(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, if modified, can extract hidden information. When a modification occurs, you can modify the location of positioning and marked maps. Logo area accounted for 75 to amend the area generally can be identified modifications)

把PCNN和非下采样结合，不仅降低了所用时间，而且提高了效率。(Under the PCNN and the sampling combination, not only reduced the time and improve the efficiency.)

包含二维广义S变换程序和测试程序，用于对图像进行时频分析。matlab版本R2011b,操作系统为32位win7。在2G内存下最大只能对84*84的图像进行处理，更大的图像会出现out of memory的问题。目前网上还没有这个程序，包括本站，pudn，ilovematlab都没有。把程序上传到这三个地方，望大家一起来改进它。(Contains a two-dimensional generalized S transform procedure and testing procedure.It is used for the time-frequency analysis of images.Matlab version :R2011b, operating system: 32 win7. Tests under 2G memory can only process 84* 84 images.A larger image will incur "out of memory" problems. This program is not found online before, including this site, CSDN, ilovematlab. Upload the program to the above three websites, hoping it improved by the help of everyone.)

说明：  在VC中实现了使用Moravec算子对遥感影像进行特征点的提取，缺点是速度较慢。不过提取效果不错！(Implemented in VC using Moravec operator of remote sensing images feature point extraction, the disadvantage is slow. However, extracting good results!)

*****将picture内的所有文件拷贝到MATLAB7.1软件下的名为word的子文件夹下********** 1.testpipei_1.m文件为基于灰度的模板匹配代码，仅为单独使用，不具有交互性 2.testpipei_2.m文件为基于灰度的快速模板匹配代码，仅为单独使用，不具有交互性 3.three.m为带有界面的演示程序，包含了上述两种算法，在MATLAB7.1中，在命令窗口下输入 edit three （three文件一定要在work文件夹下）回车后就可以进行使用了。 4.testpipei_1.m和testpipei_2.m的函数使用说明详细见各自的文件内 5.testpipei_1.m,testpiei_2.m,getOrder.m,gettezheng.m都为函数文件 three.m和three.fig共同为演示界面文件。 (Using MATLAB to image matching two images)

西安科技大学，图像处理教程的课件，做成了PDF格式，希望对你们有用(Xi' an University of Technology, image processing tutorial courseware, made the PDF format, hope that is helpful for you)

基于大气模型进行图像的去雾处理，以及均衡化的去雾处理(mage removal based on atmospheric model)

BMP,ICO,JPG等图片格式转换，按照例子可以任意格式转换(BMP, ICO, JPG and other image format conversion, according to examples can be converted to any format.)

主要介绍关于图像匹配的相应matlab程序设计(Focuses on the appropriate image matching matlab program )
