数字水印系统的通信建模
Modeling of Watermarking System as Communications
【摘要】 比较数字水印与传统通信系统的异同,从信息论的角度考察目前数字水印的通信模型,分析这些模型的优缺点,指出目前通信建模的难点,提出一种新的建模思路,为水印系统的设计提供参考。
【Abstract】 Comparisons are made between digital watermarking and classical communications.The known communication models of watermarking are investigated from the viewpoint of information theory.The nodi are analyzed and a new modeling idea is proposed to provide references for the watermarking design.
