Color and Contrast Adaptation Issues in VR Interfaces for Security Training
In this paper we present a method to reproduce color display of virtual worlds based on visual perception principles. The purpose of this technique is to solve two main problems: the tone mapping and the color recovery. Both problems arise when we aim at reproducing virtual worlds where illumination conditions are unknown and create dynamic views having a high dynamic range that has to be compressed into the limited range of a monitor or projector, and undesired color casts produced by different light sources.
