摘要
随着Internet网络的快速发展,各种多媒体内容成为主要的传输媒介,数字水印技术成为了多媒体内容保护的主要技术。文章基于内容认证手段,对数字水印模型进行总体介绍,包含数字水印实现的方法、实现的要求等。结合内容认证的手段对水印技术进行了分析,对伪随机高斯序列、二值或灰度视频水印以及归一化相关系数等进行了模型化介绍,并结合遗传算法在水印中的应用过程进行说明。
With the rapid development of Internet network,a variety of multimedia content become the main transmission media,digital watermarking technology has become the main technology of multimedia content protection.Based on the content authentication method,this paper introduces the digital watermarking model in detail,including the implementation of digital watermarking and the requirements of implementation.The analysis of watermarking technology combining content authentication method,the pseudo random Gaussian sequence,binary or gray video watermark and the normalized correlation coefficient are modeled introduced,and the application process combined with genetic algorithm in the watermark is described.
