A spatial weighting based interpolation method for DIBR

The DIBR is a novel technology used for generating virtual views has been widely used recently. However, due to imperfect depth maps, annoying artifacts appear in the virtual view images. To generate high quality intermediate virtual view images, this paper proposes a spatial weighting based interpolation method. The weighted average of mapped pixels near the integer pixel is adopted as the final interpolation value. The weighted factors of each mapped pixel are determined by the distance between its position and the current integer pixel´s position, and its depth value. Extensive experiments show that the proposed method acquires a satisfying rendering effect both subjectively and objectively.
