Abstract :
Free-viewpoint video is to enable the viewer to choose arbitrary viewpoints for the scene captured by a multi-view imaging system. In this paper we present a multi-layered variate-resolution sampling technique for 3D scene representation. The 3D point cloud obtained from the reconstructed 3D scene is used for novel view rendering. For any given viewpoint, image synthesis with different level of detail is carried out using the quadtree based non-uniformly sampled 3D data points. Experimental results are presented using the 3D model of a reconstructed real object.
