N2 - Depth-Image Based View Synthesis (DIVS) is considered as a good method to reduce the view numbers for multiview and 3DTV. However, it can't guarantee the quality of occlusion areas of the produced views. In order to reduce the view numbers for multiview and 3DTV, a novel depth-image based view synthesis scheme is proposed to produce four views by one view with depth. Artifact detection and repair functions are added to resolve occlusion areas problem. Artifact region is detected by comparing with original view, and repair function utilizes motion compensation technique to fix it from its previous virtual view. This repair function can correctly fix the artifact region at the cost of some additional bits for each virtual view. In our experiments, only one view is applied to produce four virtual views. About 4∼6 dB gain can be achieved at the costs of some additional bit stream. The total bit rate of the four views is only 56% of one color image at the same QP.
