Spatiotemporal model for the contrast sensitivity of the human eye and its temporal aspects

摘要

Abstract: The physical model for the spatial contrast sensitivity of the eye that we presented in a previous paper is extended to the temporal domain by making some assumptions about the temporal behavior of the photoreceptors and the lateral inhibition in the ganglion cells. In this way a complete spatio-temporal model is obtained that gives a simple explanation of the complicated spatio-temporal behavior of the eye. Spatio-temporal and temporal contrast sensitivity curves calculated with the model are compared with measurements published in literature. !23
