New Ray-Space Interpolation Method For Free Viewpoint Video System

Ray-space representation is the main technology to realize Free Viewpoint Video (FVV) system with complicated scene. Ray-space data consists of various lines with different direction. Ray-space interpolation and compression are two key techniques to be solved. In this paper, correlations between multiple epipolar lines in the Ray-space data is analyzed, and a new algorithm of Ray- Space interpolation with multiepipolar lines matching is proposed. Experimental results show that the proposed scheme achieves higher PSNR than the pixel-based matching interpolation method and the block-based matching interpolation method in interpolating the ray-space data and rendering arbitrary viewpoint image.
