Human color discrimination models for devices with wide color coverage and high dynamic range

Human color discrimination models (CDM) are important to ensure the accuracy of color reproduction. Currently, high dynamic range (HDR) and wide color gamut (WCG) monitors are becoming increasingly popular, but the models used in them have not previously been tested for adequacy in these conditions, since there is no such data in published datasets. Moreover, the non-geodesic structure of the perceptual color space requires datasets that cover color differences of different scales, while most existing datasets emphasize only small and threshold CDs. The report will describe the work carried out at IPPI RAS to collect a new set of data and develop a new model trained on this data.
