视频水印matlab源码，此为第三个压缩包，在水印领域的爱好者可以下载作为参考...

文件处理、画图、编辑、图像变换、颜色处理和图像处理-Document processing, drawing, editing, image conversion, color processing and image processing

这是基于OpenCV的SIFT特征提取实现。-This is based on the OpenCV implementation of the SIFT feature extraction.

可加载多种类型图片,具有多种图片展览效果-Many types of images can be loaded with a variety of photo exhibition results

彩色图像做差运算，并分RGB 以及亮度进行直方图统计，计算得到二阶导数为零的点，完全自主创作，效果理想-color image so poor operation and the hours for RGB and luminance histogram statistics, calculated second-order derivative of the zero point, entirely independent creation, the result is satisfactory

此算法是基于小波变换特征提取方法的图象匹配-this algorithm is based on the wavelet transform, feature extraction, image matching method

一个简单的IDL编写的Modis几何校正批处理，可以选择一个文件夹内所有HDF的modis数据的几何校正。-A simple IDL batch prepared by Modis geometric correction, you can select a folder of all the HDF data, geometric correction of the modis.

vc编写三惟投影变换以及二为线段以及多边形裁减！-A 3D projection transform,2D segment of line and polygon cut down programed with vc

此算法是基于小波变换模极大的多尺度图像边缘检测-this algorithm is based on the wavelet transform modulus maxima Multiscale Edge Detection

人的脸部跟踪，自动分析锁定人的脸部区域，VC++ 实现。-Face Detecting

利用数字水印技术能够对数字作品实现有效的版权保护。目前的数字水印技术大多都是针对多媒体数据。但是在地理信怠系统中除了橱格数据外, 还存在大的矢童数据。目前的数字水印算法仅仅能满足橱格数据, 无法满足在矢童数据中嵌入水印的需求。本丈在分析数据特汽的基础上, 在矢童数据的频城提出了一套行之有效的数字水印算法。-The use of digital watermarking technology for digital works to achieve an effective copyright protection. At present, most of the digital watermarking technology are targeted at multimedia data. However, in the geographical letter except idle system cabinet grid data, there are still a big child vector data. At present, only the digital watermarking algorithm can satisfy the cupboard grid data, unable to meet the child in the vector data embedded watermark needs. Zhangting data in the analysis of this special steam on the basis of the data in the frequency of vector Tong City proposed a set of proven digital watermarking algorithm.
