Abstract

A video decoding method comprises warping different viewpoint images into a virtual viewpoint by using depth information of an input viewpoint; determining a first weight for the pixels based on quality and depth of pixels of the warped viewpoint images; determining a second weight for the pixels based on a location relation between the pixels of the warped viewpoint images and the virtual viewpoint; determining a blending weight for the pixels based on the first weight and the second weight; blending the warped viewpoint images according to the blending weight; and synthesizing an image of the virtual viewpoint based on the blended viewpoint images.
