An improved multiview stereo video FGS scalable scheme

Abstract

A multiview stereo video FGS (Fine Granular Scalability) scalable scheme is presented in this paper. The similarity among adjacent views is fully utilized, A tradeoff scheme is presented in order to adapt to different demands of Quality First (QF) and View First (VF) of the decoder. The scheme is composed of three cases: I, P, B frame. The middle view is encoded as the basic layer, while the other views are predicted from the partly retrieved FGS enhancement layers of adjacent views. The FGS enhancement layer of the current view is generated based on that. Experimental results show that the presented scheme is of more flexible and extensive scalable characteristic, which could better adapt different demands on view image quality and stereo immersion of different users.
