A Novel Approach to Depth Image Based Rendering Based on Non-Uniform Scaling of Depth Values

Abstract

Depth image based rendering (DIBR) is one of the key technologies to realize future three dimensional television (3DTV) systems. In this paper, we propose a novel depth image based rendering system for stereoscopic view generation. Existing method of parallax calculation based on uniform scaling of depth values can lead to artifacts in the 3D view. We propose a method of parallax estimation based on non-uniform scaling of depth values via histogram analysis of depth map. Experimental results showed that the proposed method minimizes aforementioned artifacts while maintaining sufficient depth quality.
