摘要
论述了数字水印的基本原理,版权保护对数字水印技术的特殊要求,提出了一种基于HVS的彩色图像数字水印改进算法。该算法对原始彩色水印图像进行了置乱加密预处理,提高了水印抵抗攻击的能力,从而对图像的版权起到保护作用。
The principle of the digital watermarking and the special requirement of copyright protection was introduced. An improved digital watermarking algorithm for color images based on HVS was put forward. It scrambles the original watermarking image in pretreatment and improves the ability against attacks of the watermarking, so as to protect images copyright.
