摘要
给出了一种新的基于小波变换和视觉模型的彩色图像数字水印算法.该算法利用人眼视觉模型的特征在离散小波变换域中嵌入水印,在水印提取过程中提出一种基于分类的方法,使得图像在受到攻击时能够更好地还原水印信息.
A new method of digital watermarking for color images based on DWT and HVS is proposed in the paper.The method uses HVS model to embeds watermark in discrete wavelet transform area.And it applies the way of departing groups instead of simple averaging in detecting the watermark.The method makes the watermarking be better recovered when the images are attracted.
