| 摘 要： | 为了有效地保护数字媒体的版权,提出了一种基于小波的自适用量化的水印算法,使水印算法能确定水印的最优嵌入能量来量化小波系数,实现了水印不可感执行和鲁棒性之间的折衷,同时,水印的提取无须求助于原图像,很好地实现了水印的盲检测.实验结果和攻击测试表明,提出的算法对JPEG/JPEG2000压缩、添加噪声、剪切、亚抽样、低通滤波等多种攻击有较强的鲁棒性.

| Abstract: | Digital media copyright can be protected with a novel wavelet adaptive quantization algorithm for digital image watermarking.We can determine the best energy or capacity to be added to the original image.Experiments and attack test have showed that the algorithm has good robustness on JPEG/JPG2000,additive noise,median filter,sub-sampling,gaussian low pass filter etc. |
