Visual perception and natural illumination

Visual perception and natural illumination
Visual perception and natural illumination
We review recent work on the role of natural illumination in human vision. We discuss research showing that visual perception depends on stable statistical properties of natural light in order to solve the under-constrained problem of estimating the shape, colour, and material properties of surfaces and objects. We focus on assumptions about the distribution of luminous flux over 3D directions and spatial locations. We also review work showing that implicit assumptions about lighting colour may explain the remarkable individual differences in percepts of #thedress. We conclude by discussing the unsolved problem of how the human visual system represents lighting, and outlining promising directions for future work that have been made possible by recent advances in physically based rendering and light measurement.

Abstract

We review recent work on the role of natural illumination in human vision. We discuss research showing that visual perception depends on stable statistical properties of natural light in order to solve the under-constrained problem of estimating the shape, colour, and material properties of surfaces and objects. We focus on assumptions about the distribution of luminous flux over 3D directions and spatial locations. We also review work showing that implicit assumptions about lighting colour may explain the remarkable individual differences in percepts of #thedress. We conclude by discussing the unsolved problem of how the human visual system represents lighting, and outlining promising directions for future work that have been made possible by recent advances in physically based rendering and light measurement.
