摘要
数字水印技术是近年来国际学术界研究的重点内容之一,作为该技术领域中的一个重要分支结构,数字水印信息隐藏技术在版权保护上起着重要作用.根据以往工作经验,对数字水印隐藏模型进行阐释,并从数字水印的生成算法、小波域内数字水印的嵌入算法、小波域内数字水印检测算法三方面,论述了小波变换的数字水印检测算法的具体计算方式.
The digital watermarking technology is the research focus of international academic in recent years. As an important branch structure in the field of this technology,the digital watermarking information concealment technology plays an important role in copyright protection. In this paper,the model of digital watermarking concealment is interpreted based on the previous work experience,and the specific calculation method of digital watermark detection algorithm based on wavelet transform is discussed from the three aspects of the digital watermark generation algorithm,the digital watermark embedding algorithm in wavelet domain,and the digital watermark detection algorithm in wavelet domain.
