摘要 基于奇异值分解在图像处理中的特性,提出了一种鲁棒性较强的图像融合水印算法.再充分利用视觉感知的各种掩蔽特性进行保密信息的嵌入,使水印有很强的不可视性.并且本方案仅选择了中频小波域进行融合,从而提高了对于JPEG压缩,剪切等攻击的抵抗能力. Based on characteristics of SVD in image processing, a robust image fusion digital watermarking algorithm is proposed in this paper. Taking full advantages of all kinds of masking characteristics of human visual system, the secret information is embedded invisibly. And selecting middle frequency subbands of DWT to fuse will improve the ability of a watermark to resist or survive attacks such as JPEG compression and cutting etc.
