Description: 基于小波零树特性的视觉感知度模型的优化方案, 给出了两种水印算法: 一种算法嵌入的是高斯序列水印, 通过相关检测实现盲检测 另一种算法嵌入的是二值图像水印, 水印的提取是非盲提取。这两种算法在所有重要小波系数( 包括最低频系数) 中嵌入水印, 以达到最大化水印嵌入量的目的, 并结合感知度模型在水印的透明性和鲁棒性之间实现了较好的平衡, 对于常见的图像处理操作, 特别是对于JPEG 和小波压缩均有较好的鲁棒性。-based on wavelet zerotree visual perception characteristics of the model optimization program, and presents two watermarking algorithm : An algorithm is embedded watermark Gaussian sequence, through correlation detection achieve a blind detection algorithm embedded in the binary image watermark, the watermark extraction from non-blind. These two important algorithm in all wavelet coefficients (including most low-frequency coefficients) embedded watermark, to maximize embedding of purpose, and perceptual model with the watermark of transparency and robustness between a good balance, for common image processing, particularly for JPEG and wavelet compression has better robustness.

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: |
