基于JPEG2000及HVS的自适应水印算法

Adaptive watermark algorithm based on JPEG2000 and HVS

提出一个基于JPEG2000的自适应水印算法。该算法结合了EBCOT的编码特点及HVS特性,在量化的系数中筛选重要系数实现水印嵌入,使嵌入图保持良好的视觉效果,也使嵌入的水印信息在经历EBCOT编码后仍具有较强的鲁棒性。

An adaptive watermark algorithm based on JPEG2000 is proposed in this paper. Using of the characteristics of EBCOT and HVS, the algorithm selects the important coefficients to embedding watermark. Therefore, the Visual effect of embedded image is fine and the watermark information is robust through EBCOT.
