论文摘要
可逆音频水印(RAW)是各种应用中的一种有前途的技术。为了同时满足实现高度易于识别和鲁棒性的需求,本文提出了一种基于晶格的新型原始方案。该方案称为中间嵌入(MME),其中晶格量化错误适当缩放并添加回量化的主机信号。模拟表明,MME在广泛的指标中脱颖而出,包括信噪比比率(SWR),客观差等级(ODG)和位错误率(BER)。
Reversible audio watermarking (RAW) is a promising technique in various applications. To simultaneously meet the demand of achieving high imperceptibility and robustness, this paper proposes a novel RAW scheme based on lattices. The scheme is referred to as Meet-in-the-Middle Embedding (MME), in which the lattice quantization errors are properly scaled and added back to the quantized host signals. Simulations show that MME excels in a wide range of metrics including signal-to-watermark ratio (SWR), objective difference grade (ODG), and bit error rate (BER).
