| 摘 要： | 提出了一种基于小波变换域的盲检测数字水印算法.对载体图像进行二级小波变换,以一级小波变换中的水平细节子带系数为参考,自适应地调整同方向二级小波系数来实现水印信息的嵌入.实验结果表明,嵌入的水印具有较好的透明性和鲁棒性,并且可实现水印信息的盲提取.

| Abstract: | A blind watermaking algorithm based on wavelet transform domains is proposed.The original image is added a two-level wavelet transform.The coefficients of horizontal particular sub-band in on one-level wavelet transform are referenced to adjust the two-level wavelet coefficients in the same direction adaptively,and at the same time the watermark information could be embedded.The results show that the embedded watermark has good transparency and robustness,and the watermark is extracted from the watermarked ... |
