Multiview video can bring the 3D and virtual reality perceptual experience to users by its multiple view point characteristic. To support the smooth and free view point switching, both matrix-based depth image based rendering and the complex virtual view interpolation schemes are required. In order to reduce the high computation complexity and avoid the iterative processing scheduling in conventional view interpolation flows, a single iteration view interpolation algorithm is proposed. By use of the proposed algorithm, the redundant warping operations are reduced by 86%. In addition, based on the proposed artifact detecting and removing algorithm, artifacts due to imperfect depth maps can be detected and eliminated at the same time. Therefore, no additional post-processing or iteration is required and the single iteration processing is achieved.
