Abstract: A general watermarking framework based on human visual system (HVS), named HGWF, is proposed, and a mathematical description of it is presented through a nine-tuple. Two conceptions-the perceptual similarity and watermark equivalence are defined here. Also, a general description of digital watermarking scheme is delivered based on cryptography and HVS. Furthermore, the definition and character of watermark and the key technique are described based on HGWF. ;;;

摘要： 建立了基于人类视觉系统(HVS)的图像数字水印理论框架(HGWF),并用一个九元组给出了HGWF的数学描述,定义了水印知觉相似性和水印等价,对基于密码学和人类视觉特性的数字水印方案,给出了一种通用的描述方法。基于HGWF,进一步对水印的基本定义、关键技术、水印的特点和要求等进行了描述。
