Description: 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! Platform: |
