一种基于DCT的数字水印算法∗
Digital Watermarking Algorithms Based on DCT Transform
摘要
Abstract
This article first introduces the background of the development of digital watermarking technology,then the classifi?cation and basic characteristic of the digital watermarking,model,characteristics,application and so on has carried on the simple, common algorithm is introduced. Secondly,this paper discusses DCT algorithm of digital image watermark embedding and extrac?tion of desirability and effect,etc. And then through the Matlab simulation to achieve the specific process,finally through experi?ment contrast analysis and summarizing,it is concluded that the algorithm has certain feasibility and good robustness.关键词
