| 摘 要： | 基于Nelson等的时空域可见水印算法,提出一种利用超大规模集成电路(Very Large Scale Integration)实现在数字媒体中添加可见水印的模型,文中数字媒体以数码相机为例,首先根据Mohanty等人提出的数字图像水印算法对其进行简化,然后设计相应的硬件实现模型.此芯片模型的设计是采用自底向上的分层结构,单独设计基本运算单元模块,再通过接口将相关单元整合,而最底层的电门采用互补金属氧化物半导体(Complemen-tary metal-oxide-semiconductor)标准单元的设计方法.

| Abstract: | This work focuses on the spatial domain visible watermarking scheme, which was proposed by Mohanty. A feasible model of very large scale integration is presented to implement a visible digital image watermarking scheme.Taking existing digital still camera for example,the predigested scheme is realized. The chip model uses the bottom-to-up hiberarchy. The basic operation units are designed individually;and then integrated into models through interface. The bottom gates employ the basic unit design of complementary metal oxide semiconductor. |
