基于CIELUV的新均匀颜色空间MLUV的研究

A New Uniform Colour Space MLUV Based on the CIELUV

本研究通过修改CIELUV的明度、色度坐标,红-绿和黄-蓝坐标,建立一个新的均匀颜色空间,即MLUV。使用COM数据集进行的性能测试表明,MLUV的性能明显优于CIELAB、CIELUV和MLAB颜色空间。虽然CIEDE2000在预测所有视觉色差数据集方面明显优于MLUV,但前者只是一个色差公式,后者是一个统一的颜色空间。因此,MLUV有望用于颜色变化分析和色差评估,特别是在依赖于光的添加混合的工业领域,如彩色电视机、视频监视器和照明。

In this study,a new uniform colour space MLUV was developed by modifying the lightness,chromaticity coordinates,and red-green and yellow-blue coodinates for the CIELUV.Performance test using the COM dataset showed the MLUV performed significantly better than the CIELAB,CIELUV and MLAB colour spaces.Though CIEDE2000 is significantly better than the MLUV in predicting all the visual colour difference datasets,the former is only a colour difference formula and the latter is a uniform colour space.Hence,it is expected that the MLUV can be used for colour variation analysis and colour difference evaluations,especially in industrial fields that depend on the additive mixing of light,such as in color TV sets,video monitors and illuminations.
