Abstract

Experiments using real images are conducted on a variety of color constancy algorithms (Chromagenic, Greyworld, Max RGB, and a Maloney-Wandell extension called Subspace Testing) in order to determine whether or not extending the number of channels from 3 to 6 to 9 would enhance the accuracy with which they estimate the scene illuminant color. To create the 6 and 9 channel images, filters where placed over a standard 3-channel color camera. Although some improvement is found with 6 channels, the results indicate that essentially the extra channels do not help as much as might be expected.
