摘要

提出了一种基于在量化数据域中嵌入标记的组合水印和压缩算法。这种方法在鲁棒性、不可见性、嵌入容量和压缩比特率之间取得了很好的平衡。此外,提取过程不需要知道压缩参数,即使是被攻击的图像。这就产生了一种与比特率无关的水印算法。

Bit-rate adapted watermarking algorithm for compressed images
We propose a combined watermarking and compression algorithm based on the embedding of the mark in the quantized data domain. This approach offers a good tradeoff between robustness, invisibility, embedding capacity and compression bit rate. Furthermore, the extraction process does not need knowledge of the compression parameters, even for attacked images. This leads to a watermarking algorithm which is bit-rate independent.
