Abstract
Ray-Space representation has superiority in rendering arbitrary viewpoint images of complicated scene in real-time. Ray-Space interpolation is one of the key techniques to make Ray-Space based Free Viewpoint Television (FTV) feasible. This paper presents a directionality based interpolation method for Ray-Space based FTV system, in which characteristic pixels are first extracted from sparse Ray-Space slice, and their directionalities are determined by block matching, while directionalities of other pixels to be interpolated are obtained by interpolating with the directionalities of these characteristic pixels. Experimental results show that the proposed method improves visual quality as well as PSNRs of rendered intermediate viewpoint image greatly.
