摘要
本文提出了一种基于噪声可见函数(NVF)量化的水印算法。该算法用噪声可见函数NVF最大化水印能量,在嵌入时使用多重嵌入技术,增加了水印的不可见性和鲁棒性,水印在提取和检测时不需要原图信息。
In this paper, we propose a digital image watermarking algorithm using the noise visibility function（NVF） based on wavelet quantization. The watermark is multi-embedded with an adaptive watermark strength according to the computation of the noise visibility function , which improves the invisibility and robustness of the watermarking algorithm.The original image information is not needed in the extraction and detection of watermarks
