dc.description.abstract | Chromagenic color constancy is one of the promising
solutions to the color constancy problem. However, this
technique requires two shots of a scene: a conventional RGB
image and an additional image that is optically pre-filtered
using a chromagenic filter. This severely limits the usefulness of
chromagenic based color constancy algorithms to static scenes
only. In this paper we propose a solution to this with the use
of a digital stereo camera, where we place the chromagenic
filter in front of one of the lenses of the stereo camera. This
allows capturing two images of a scene, one unfiltered and
one filtered, in one shot. An illuminant can then be estimated
using chromagenic based illumination estimation methods. Since
more and more digital stereo cameras are being commercially
available, the system can be built quite easily, and being a one
shot solution, it is a practical computational color constancy
method that could be useful in many applications. Experiments
with a modern commercial digital stereo camera show promising
results. | no_NO |
