数字水印处理系统主要由水印嵌入和水印检测两个过程。（1）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*）。 （2）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。该程序调试已通过！-Digital watermarking system mainly consists of watermark embedding and watermark detection of the two processes. (1) The watermark embedding process as follows: Digital watermarking (X), the original image (I) and key/public key (K) by digital watermark embedding algorithm to form watermarked image (I*). (2) The watermark detection process is as follows: Digital watermarking (X), the watermark image (I*) and key/public key (K) by digital watermark detection algorithm to detect whether the digital watermark or watermark. The program debugging has passed!

一个菜单界面，分别用菜单命令来绘制原数据曲面图，线性插值，最近点插值，3次多项式插值，3次样条插值后的图形，每次插值都可以在同一图形界面下比较插值前后图形。-A menu interface, respectively, using the menu command to map the original data surface map, linear interpolation, nearest point interpolation, polynomial interpolation 3 times, 3 times after spline graphics, interpolation can be per- under the same graphical interface graphics compared before and after interpolation.

OpenCV的特征比较和匹配，使用不同的方法

用matlab实现的有一个数字水印程序，它也是基于dct算法的数字水印程序，对一副图像进行dct变换然后嵌入水印-using Matlab is a realization of the digital watermarking procedure, which is based on the A1501 digital watermarking algorithm procedures, a pair of images Extra Transform then embedded watermark

其中包括idct10、idct14、idct20、idct36的汇编代码-Including idct10, idct14, idct20, idct36 assembly code
