A hybrid color matching between stereo image sequences

The interest in the production of stereoscopic contents is growing rapidly. High quality stereo material can be produced using vertical stereo camera rig but complex color discrepancies occur because of the optical characteristic of the half mirror. These discrepancies may severely increase an audience´s sense of fatigue if s/he watches these stereoscopic contents for a long time. The color matching methods often considered in the post-processing stage of stereoscopic production are mainly based on global transformations between the two views, but this approach can not completely recover local color inconsistency. We propose a new color matching method to correct local and global color discrepancies. We used prior knowledge about the vertical camera rig, SIFT feature matching and pyramid optical flow and modified histogram matching. Experimental results proved the effectiveness and the robustness of our algorithm.
