Abstract
We have proposed the Free-Viewpoint Television (FTV) which enables a viewer to select arbitrary viewpoints using Ray-Space method. Ray-Space requires a tremendous amount of data made from multiple camera information, and needs to be greatly compressed. So far, we have investigated compression methods in linear camera arrangement. In this paper, we propose a new compression method based on sub-sampling and interpolation in a circular camera arrangement. Hierarchical and sequential interpolation with/without residual error coding were compared. Experimental results showed that the hierarchical interpolation gives the better coding efficiency than sequential one.
