| 摘 要： | 文章提出一种基于量化的嵌入DCT域直流分量的数字水印算法。该算法以二值图像为水印,根据JPEG标准量化表系数确定水印嵌入强度,提取时不需要宿主图像。实验表明:该算法简单易行,对常见的水印攻击有较好的鲁棒性和实效性。

| Abstract: | In this paper a new Algorithm For Blind Watermarking embedding in DC components of DCT based on quantification is presented.Using a binary image as the watermarking,the intention of embedding watermarking is based on the JPEG quantitative table and the retrieval of watermarking need not original image.The experiment result show that this algorithm is easy to perform and robust to most common signal processing attacks and can meet demand of the watermarking to a certain extent. |
