ab: Summary: Free viewpoint television (FTV) based on ray-space representation
    was adopted in the MPEG draft because the ray-space can generate an
    arbitrary viewpoint view without complicated analysis and rendering
    process. Ray-Space predictive coding is one of main techniques in
    ray-space based FTV systems, in which block matching and compensation
    plays a very important role to improve coding performance. However, the
    computational burden of block matching for ray-space coding is the
    problem to be solved. Ray-space representation of FTV is introduced and
    inter-slice correlations of ray-space data are analyzed. Then, a fast
    adaptive block matching algorithm for ray-space predictive coding is
    proposed to reduce the encoding complexity. Experimental results show
    that the proposed block matching method reduce the computational burden
    and speed up the coding process greatly.
