摘要
该文提取了一种基于噪声可见函数(NVF)量化的水印算法。该算法用噪声可见性函数NVF最大化水印能量,并将经过NVF处理后的水印嵌入到小波域中。水印的提取采用了快速固定点独立分量分析(FastIcA)的办法进行盲提取。仿真实验表明该算法对于常见攻击方式具有较强的鲁棒性。
we propose a scheme for blind watermarking of digital images using the noise visibility function (NVF) based on wavelet quantization. The watermarking is embedded with an adaptive watermarking strength according to the computation of the noise visibility function. The watermark is extracted resorting to FastlCA. The results of emulation have shown its robustness against may attacks.
