Abstract

Because of scene illumination or camera calibration, color appearance of the same object between different viewpoints may be different in multiview video system. Traditional illumination compensation algorithm for image is unable to solve this problem effectively. In this paper, a novel color correction method for multiview video system is proposed based on retinex color constancy theory. To eliminate influence of un-consistent light sources, histogram equalization, retinex processing and color restoration are performed for multiview images to extract reflectance that describes object intrinsic properties. Experimental results show that the proposed image correction method for multiview video system is effective
