Variable quantizing robust digital watermarking algorithm based on image content sensibility analysis
基于图像内容敏感度分析数字水印算法

Most of recently image watermarking algorithm is based on image texture analysis. In practice, content and taste of observer are very important information for determining embedding points. This paper presented a novel digital image watermarking algorithm based on content sensitivity analysis in. Developed a new method which successfully combines the characteristics of singular values and variances to measure the activity of sub-blocks of the host image. The application of the proposed embedding scheme made...
