A color constancy algorithm using photodetector characteristics of a camera for indoor scenes

Abstract

According to a recent research, illumination invariant features could be available to guarantee robust and reliable performance of vision systems. The research incorporated the imaging sensor properties to the vision algorithm, which is a general case in robotics contexts. However, these features are only applicable for the outdoor scenes. This paper develops an algorithm that enhances the features reported in the previous research. The features work for the indoor scenes with the proposed algorithm. Experiments are conducted to verify the performance of the proposed algorithm. It is verified that the features enhanced by the proposed algorithm become robust to illumination fluctuations.
