A New Conversion Algorithm between Munsell Color Order System and CIE1931 Standard Colorimetric System

The automatic conversion between Munsell color order system and CIE1931 standard colorimetric system is an important issue in the field of color and vision.A novel conversion algorithm between these two color systems based on the constant hue and chroma loci is proposed in this paper.The forward conversion from Munsell color order system to CIE1931 standard colorimetric system reaches the accuracy of ΔY=0.004,Δx=0.000 13,and Δy=0.000 13. And the backward conversion from CIE1931 system to Munsell system reaches ΔV≈0,ΔH=0.017 5,and ΔC=0.013.
