摘要
本文简单介绍了鲁棒水印技术和离散余弦变换的概念,并以Matlab作为开发环境,结合数字水印技术,介绍了一种基于DCT域的鲁棒水印算法,结果证明,这种算法达到了很好的不可见性和很强的鲁棒性。
This article introduced simply the robuse watermark technology and the discrete cosine transform concept, and by Matlab took the development environment, the union numeral watermark technology, introduced one kind based on the DCT territory robust watermark algorithm, finally proved, this algorithm has achieved the very good invisibility and the very strong robustness,
