Four issues concerning colour constancy and relational colour constancy
Four issues concerning colour constancy and relational colour constancy are briefly considered: (1) the equivalence of colour constancy and relational colour constancy; (2) the dependence of relational colour constancy on ratios of cone excitations due to light from different reflecting surfaces, and the association of such ratios with von Kries' coefficient rule; (3) the contribution of chroma...
متن کاملColour constancy
What is colour constancy? Colour constancy is the tendency of objects to appear the same colour even under changing illumination. A yellow banana appears yellow whether you see it in the tungsten light of the kitchen or in sunlight outdoors. Under these different conditions, the banana reflects very different light spectra to your eyes, but you see instead its unchanging material properties. Th...
متن کاملMultispectral Colour Constancy
Does extending the number of channels from the 3 RGB sensors of a colour camera to 6 or 9 using a multispectral camera enhance the performance of illumination-estimation algorithms? Experiments are conducted with a variety of colour constancy algorithms (Maloney-Wandell, Chromagenic, Greyworld, Max RGB, and a Maloney-Wandell extension) measuring their performance as a function of the number of ...
متن کاملReflections on colour constancy.
F or more than two centuries, scientists and artists have come up with a range of ways to demonstrate that the wavelength composition over a whole scene can affect how we perceive the colour of the individual parts of that scene. The proportion of light of each wavelength reflected from an object can be highly beneficial in detecting or recognizing objects 1. However, to make use of that invari...
متن کاملRethinking Colour Constancy
Colour constancy needs to be reconsidered in light of the limits imposed by metamer mismatching. Metamer mismatching refers to the fact that two objects reflecting metameric light under one illumination may reflect non-metameric light under a second; so two objects appearing as having the same colour under one illuminant can appear as having different colours under a second. Yet since Helmholtz...
