3-D scene representation with layered non-uniform global sampling

The representation of a 3-D scene is essential to recent multi-view imaging technologies. In this paper we propose a unified geometry and texture representation based on global resampling of the scene. The 3-D coordinates and the associated texture information of the scene points are represented in the polar coordinate system. A novel layered data map representation with distance-dependent nonuniform sampling strategy is proposed to deal with complex scenes. It is capable of increasing the details of the 3-D structure locally and thus is compact in size. The experimental results on synthetic data sets and real images are presented.
