摘要：In this paper, we propose a novel data compression scheme based on ray-space coding for 3-D spatial information. By using a spatially uniform sampling method for the sampling of the ray-space and estimating the amount of ray-space data, we can efficiently reduce the redundancy of the ray-space data through disparity compensating predictive coding. From this viewpoint, we propose a novel predictive coding scheme which utilizes the geometrical relationship between orthographically projected view images. In our experiment, a compression ratio of 1/100 with PSNR 27 dB is obtained for computer-generated ray-space data.
