彩色图像对比度定义的探讨

Discussing the defination of color image contrast

在前人研究对比度的基础上,对对比度公式进一步修改、分析和讨论,提出一种把彩色图像分解为灰度图和色度图的思想,并且找出灰度对比度、色度对比度和彩色对比度之间的关系,从而提出一个新的彩色对比度公式,并结合实验分析讨论其实用性,希望能更好地应用到纺织、印染、颜料等的研究中。

Based on the predecessors, research on contrast , we further modify, analyze and discuss in order to put forward an idea that color image can be decomposed into luminant and chromatic image , find out the relation of luminant image contrast, chromatic image contrast and color image contrast ,put forward a color contrast formula , analyze and discuss its practicability. So we hope it can be applied in the practical research of spin, printing and dyeing, pigment etc.
