视觉系统从彩色图象中提取模糊信息特性的研究

视觉系统从彩色图象中提取模糊信息特性的研究 A STUDY ABOUT HUMAN VISUAL PERFORMANCE ON EXTRACTING FUZZY INFORMATION IN COLOUR IMAGE 朱福元 Zhu Fuyuan 1 first-author 武汉大学无线电信息工程系 武汉大学无线电信息工程系 Department of Raido & Information Engineering,Wuhan Uuiversity Department of Raido & Information Engineering,Wuhan Uuiversity 本文基于彩色视觉研究的基本特点指出:可以把计算单色图象信息含景的方法推广到计算彩色图象信息含量,进而对彩色图象信息含量同彩色数之间定量关系的建立作了详细介绍。作者以计算数据及相应的曲线为根据,对影响彩色图象色彩辨识中模糊信息量的有关因素作了讨论与分析。文末以 Munsell 彩色分级系统为例,给出了在同样的信息含量下,彩色数同色调、亮度、彩度等属性的分级数之间的关系。 Based on the colour vision propery,an extending from gray tone image to colour image on calculating information content is presented in the paper. The establishment of relationship on information content to colour number used in image is introduced in detail.Some results,which related colour num- ber to numbers of Hue,Valae and Chroma in Munsell system with the same percentage of available information content,are given. 视觉系统 彩色视觉 彩色图象 模糊熵 Munsell 彩色分级系统 visual system colour-vision colour image fuzzy entropy Munsell system on colour scales 1990-01-01 2021-04-01 1
