提高DCT域水印质量的一种算法

A New Method Improving Watermark in DCT

提出了一种能提高水印质量的策略和算法,将水印图像先进行处理,分为两部分然后分别嵌入到载体图像中,有效地提高水印的质量。实验结果表明,此种算法具有良好的鲁棒性。

This paper puts forward a new strategy to improve the quality of watermarking in DCT domain.First,it splits the watermarking image into two parts.Then,the two parts are embedded into original image respectively.Experimental results show that the proposed algorithm is possessed of good robustness.
