基于人类视觉特性（HVS）的离散小波变换（DWT）数字水印算法

伴随着计算机网络通信技术的蓬勃发展，数字媒体数据的交换和传输变得日益简单且快捷.数字水印技术是一项将数字、序列号、图像标志等版权信息嵌入到数字产品信息中，用来保护数字产品版权和认证来源及完整性的新型技术.提出了一种基于人类视觉特性HVS的小波域盲数字水印算法，通过借鉴人类视觉特性HVS算法思想自适应的嵌入水印信息，能够很好地达到水印嵌入透明性和鲁棒性的平衡.通过Matlab软件实验仿真，表明该算法具有较好的透明性和鲁棒性.

A DWT digital watermarking algorithm based on HVS

With the development of internet, exchange and transmission of digital data become easier and faster than before. The technology of digital watermark is a new technique for protecting the copyrights of digital products by embedding some numbers, serial numbers or maps in original digital products. In this paper, a kind of blind digital watermark based on HVS and DWT was proposed, and this kind of algorithm could effectively achieve the balance between robust and imperceptibility in watermarked image by using HVS algorithm. It showed that the proposed al- gorithm had good property of robust and imperceptible by Matlab software stimulation experiments.
