"Folds" may appear when the depth-image-based rendering(DIBR) technique is used to generate destination image.In order to remove the folds,an approach to determine the scan order of reference image by view judgment is proposed.First,the z coordinate of epipole is set as an infinitesimal,then the scan order of reference image rendering the left or the right view is determined by the new homogeneous coordinates of epipole.Accordingly,the scan order of reference image can be determined by the destination image which is left view or right view.Experimental results show that the proposed approach can eliminate folds with less complexity in contrast to the Z-buffer algorithm,and it is adaptable to virtual view rendering when the virtual viewpoint shifts horizontally.
