二维光学刺激下的视觉感知定律

Visual perception law under bi-dimensional optics stimulation

Abstracts

人类对刺激量的感知分为数量感知和质量感知。无论是韦伯-费克纳(Weber-Fechner)的对数感觉定律还是史蒂文斯(Stevens)的幂函数感觉定律,都是关于感觉量与一维亮度刺激之间定量关系的定律。图像属于具有二维亮度分布特征的刺激量。本文研究的是二维亮度刺激的质量的感知,即二维亮度刺激质量好坏程度的感知。好坏程度是一个模糊的心理学概念,因此我们需要用模糊数学的方法来量化图像视觉感知质量的好坏程度,即建立一个模糊隶属函数PQ来定量表示图像视觉质量的好与坏的程度。
[英文摘要] Human sense of stimulus quantity is divided into quantitative sense and qualitative sense. Whether it's Weber- Fechner's logarithm sensory law or Stevens's power function sensory law are both such a law that is about the quantitative relationship between sensory quantity and one-dimensional luminance stimulus. The image belongs to the stimulus with two-dimensional distribution characteristics of the luminance. It is studied in this paper that is the qualitative sense for two-dimensional luminance stimulus, that is, the sense of the good level or bad level of the quality of two-dimensional luminance stimulus are studied. Good level or bad level is a fuzzy psychological conception, so we need to use the method of fuzzy mathematics to quantify the good level or the bad level of the visual perception quality of an image, that is to establish a fuzzy membership function PQ to quantitatively represent the good level or the bad level of the visual quality of an image.
