一种基于小波变换的图像水印算法

The Watermarking Algorithm Based on the Wavelet Transform

摘要:

目前数字水印已经成为用来解决数字多媒体中版权问题和内容认证的主要工具。本文讨论了一种基于小波变换的数字水印算法,数值模拟表明该算法较好地保持了图像的质量,并且对常用的图像处理方法有较强的稳健性,是一种能抵抗各种攻击的较稳健的水印算法。

Abstract:

Watermarking algorithm has become a primary method in copyright issue and content authentication of digital multimedia.A watermarking algorithm based on the wavelet transform is discussed in this paper.Numeric simulation indicates that this algorithm can
