Simulation of color afterimages: An approach to computing virtual color perception

Abstract

Afterimages are a common and frequent perceptual phenomenon of everyday life. When looking into a high-intensity light source and suddenly turning away from it, a temporary ``ghost'' of the light source remains visible, for a while. The computer-graphics simulation of afterimages is based on biophysical and mathematical models as published in the literature. A subordinate of afterimages defined in our research is virtual color perception, that is in our interpretation an unusual and intense temporary color perception provoked by a rapid change in the color of the incident light. In research, the modelling of virtual color perception is a field that is by and large untouched. Our publication presents a kinetic model established to characterize the intensity and duration of virtual color perception as a function of rapid changes in the color of the incident light.
