Abstract

This paper proposes a new approach for the image-based rendering (IBR) problem. IBR has many potential applications such as remote reality, telepresence in which traditional computer graphic techniques require high computational complexity. Our algorithm proactively propagates all available information from actual cameras to virtual cameras, using a depth availability assumption. This process turns the IBR problem into a nonuniform interpolation problem at the virtual camera image plane, which can be done efficiently at once for all image pixels. Experimental results show the proposed algorithm has low computational complexity and produces accurate rendering, especially around object boundaries-where most of existing methods fail.
