基于扩频通信的数字水印

Watermarking based on spread spectrum technique

基于扩频通信在通信技术中的重要应用,以及数字水印不可见性与水印加载强度很难控制的情况,本文提出一种利用扩频通信技术的数字水印算法。通过实验证明,本算法可以在一定程度上确定特定的水印加载极限强度,获得良好的鲁棒性。

Based on the important implication of the spread spectrum communication technique,and the hard control of the digital watermarking＇s invisible and robust.This article put forward a watermarking based on spread spectrum technique,experiment results show that to a certain extent,this Algorithm confirm the specific watermark loads the intensity of limit ,we may have good robust.
