weighting tables of cie tristimulus values for industrial application

面向工业应用的CIE三刺激值加权表

in color matching experiments, and the area under test color to color, with the number called tristimulus values.

在颜色匹配实验中，与待测色达到色区配时所需的数量称为三刺激值。

The calculation of theoretical "screen effect ''" from the viewpoint of mutual matching of spectral tristimulus values of a CIE standard colorimetric observer with color negative films and color printing papers is described in this article.

本文从彩色负片、彩色相纸与CIE标准色度观察者光谱三刺激值相匹配的角度出发，对理论银幕效果进行了推导。

Since the spectrum property of the three primary colors used in the color LED display screen has a great difference from that of the color television system, the same color has different tristimulus values in the two different three primary colors chrominance systems.

由于彩色LED显示屏所选用的三基色与电视系统三基色在光谱特性上有着较大差别，同一颜色在2个不同的色度系统中，其三刺激值必然不同。

a new spectral pattern method of medicine color standard which breakthrough the traditional way of color tristimulus values is given.

提出一种药剂颜色标准的谱识别新方法，该方法突破了传统的三刺激值测色模式。

testing of paper and board; determination of tristimulus values, tristimulus method

纸和纸板检验。按三区段法对标准色值的测定

tristimulus values: in the cie colour systims, the amount of red green and blue light required to make up a given colour.

三刺激值：在国际照明委员会所用的表色法内，造成某个颜色的红、绿、兰光的份量。

It takes much time to detect edges of color images directly. To resolve this problem, reduce the dimensionality of color image space ( RGB), while keep the gray moments of tristimulus values invariable to reserve as much as possible the main characteristics of the original images.

针对彩色图像边缘检测计算量大的弱点，对彩色图像空间（RGB）进行三基色降维处理，保持图像的各个基色的灰度矩不变，以最大限度地保留原图像的主要特征。
