摘　　要：在信息时代,数字图像成为人们储存信息、传播知识和分析问题的重要媒体。但是,随着网络技术的发展和缺乏相应的监督技术,在网络中传播的数字图像极易被恶意盗用和非法篡改。在缺乏技术保障的情况下,图像的拥有者很难维护自己的所有权。为了解决这一问题,数字水印技术应运而生。本文提出了一种在小波域内综合考虑人的视觉特性和鲁棒性的水印算法,该算法简单方便、效果好。Digital image has become an important medium for people to store information, disseminate knowledge and analyze problems, especially in the information age. However, with the development of network technology and the lack of corresponding supervision technology, the digital images which are transmitted in the network are very easy to be stolen and tampered. The owners of the image are hard to maintain their ownership without technical support. The increasing development of digital watermarking technology is to solve this problem. In this paper, a watermarking algorithm based on human visual properties and robustness in wavelet domain is proposed.
