Publikováno v: i-Perception, Vol 15 (2024)

The “Color Circle” is an important chromatic Gestalt in the visual arts. There is not really a formal equivalent in conventional colorimetry. The fact that the hues can be linearly ordered and that such an order is necessarily periodic was intuit

Estimating the Illumination Direction From Three-Dimensional Texture of Brownian Surfaces

Autor: Sylvia C. Pont, Andrea J. van Doorn, Jan J. Koenderink

Publikováno v: i-Perception, Vol 8 (2017)

We studied whether human observers can estimate the illumination direction from 3D textures of random Brownian surfaces, containing undulations over a range of scales. The locally Lambertian surfaces were illuminated with a collimated beam from rando

Awareness of the Light Field: The Case of Deformation

Autor: Andrea J. van Doorn, Jan J. Koenderink, James T. Todd, Johan Wagemans

Publikováno v: i-Perception, Vol 3 (2012)

Human observers group local shading patterns into global super-patterns that appear to be illuminated in some unitary fashion. Many years ago, this was noticed for the case of uniform, unidirectional illumination. Recently, we found that it also appl
