视觉心理、生理因素是有效、准确评价图像质量的重要依据.尽管在计算层面已有众多视觉心理、生理计算模型及方法为其提供支持,但在图像质量评价任务中如何分析各种孤立方法之间的内在关系进而使之有效协同,是使得评价结果更符合人主观评测的关键.从图像质量评价的角度出发,功能上将人眼的视觉注意区域定义并数学形式化为视觉初期注意区域与视觉转移期的劣质区域;同时考虑人眼的感知冗余特性,结合JND感知冗余模型,进而提出了图像质量评价范畴下的视觉感知模型PVSSIM.以此为依据,将感知视觉的方法在二维图像数据库中验证其可行性,并将其引入到立体图像质量评价中.实验结果表明,提出的客观评价方法与传统方法相比,充分考虑到了图像质量评价任务中各种视觉心理、生理因素的协同,与人主观的图像质量评价相比具有更高的相关度,评价方法在立体图像库中能很好地与主观评价相吻合,达到了预期的效果.

The visual psychological and physiological factors are crucial for the assessment on image quality. There are many visual, psychological and physiological calculation models used to support the assessment of image quality, however, how to analyze the intrinsic relations among various isolated methods and further effectively coordinate them in the task of image quality assessment is the key to making the assessment results more conform to subjective assessment of human. The definition and formalization of visual attention areas as saliency in the early vision period and poorquality area for vision transformation periods were examined from an image quality angle. Simultaneously, the property of perceptual redundancy of human eyes, JND(just noticeable distortion) perception redundancy model, and vision perception model PVSSIM of image equality assessment will be examined. Based on the research findings, feasibility of vision perception methods are verified using a twodimensional image database study through the introduction of image stereoscopic. The experimental results confirm that, in comparison with traditional methods, the raised objective assessment method sufficiently considers the coordination of various psychological and physiological factors in the task of image quality assessment, it is more relevant to the subjective image quality assessment of human. In the stereoscopic image database, the assessment method may properly coincide with the subjective assessment, the expectable effect is realized.
