Andrey A. Grigoryev, Doctor of Technical Sciences, Professor. In 1981, he graduated from the Moscow Power Engineering Institute (MPEI). At present, he is the Professor of the Lighting Engineering Sub-department of NIU MPEI, the Head of the Vision Functions Research Group at Sergey Vavilov Russian Lighting Research Institute (VNISI)

Victoria A. Rybina is an assistant-teacher of the courses devoted to fundamentals of light and engineering and mathematical modelling of the threshold colour vision at Moscow Power Engineering Institute, and also she is in staff of the Russian Lighting Research Institute named after Sergey I. Vavilov (VNISI)

Abstract:

The authors developed the MatLab program for modelling the observation of an object and a background of different chromaticity at the constant luminance and obtained the uniform-chromaticity curves with shape close to elliptical. The results of colour thresholds calculations are compared with MacAdam ellipses and an explanation is given for their differences. Based on the statistical model of threshold colour vision, the authors derived expressions for the physiological uniform colour space.
