Perception-Based Rendering: Eyes Wide Bleached

Abstract

Perception issues are a key factor in rendering Vision-Realistic images. This paper develops a novel spectral sensitive model of the Human Visual System (HVS) in order to simulate the bleaching effect in retinal photopigments. First, the Stiles-Crawford effect is taken into account to determine the pupil size of the adapted eye and to compute the directional sensitivity of the photoreceptors in the retina. After that, the percentage of bleached pigment based on the incident retinal illuminance is calculated to simulate the loss of spectral sensitivity of the human observer seeing the scene.
