%X 摘要： 在基于失真不可感知的控制模型(maximize payload under imperceptive, MPUI)下,研究了空域图像的最大水印容量。发现最大水印容量不仅与嵌入强度有关,而且与图像尺寸大小、复杂度、视觉敏感度等因素相关。在理论上推导了最大水印容量与图像大小、嵌入强度的关系,并采用多元回归分析方法研究了图像复杂度、视觉敏感度与嵌入率的关系模型。综合这些内外因素,借助于主客观评价体系,推算出水印嵌入容量的估算方法,并在实验中验证了该估算方法的有效性。<br>Abstract: Based on the MPUI model, we study the maximum watermarking payload of spatial domain image, which is not only related to embedding intensity but also to the factors such as the size of image, image complexity and visual sensitively, and so forth. We derived the relationship among maximum watermarking payload, size of image and embedding intensity, and adopt multivariate regression analysis method to research image complexity, visual sensitivity, and embedding rate model. Synthesize these internal and external factors, with the aid of subjective and objective evaluation system, we estimate the estimation method of watermark embedded payload and verify its effectiveness through experiments
