Color inconsistency is an urgent problem to be solved in free viewpoint television.In this letter,a new color correction method is proposed by using disparity vector information.At first,we separate foreground and background from the scene with a method of mean-removed disparity estimation.Then the correction parameters are estimated by adopting linear fitting for foreground and background regions,respectively. Next,with expectation-maximization algorithm,we integrate correction parameters of foreground and background to get the final corrected image.Finally,video tracking technique is performed to correct multi-view video.Experimental results show that the proposed method is quite effective.
