Abstract

Depth image based rendering (DIBR) has been proposed to create content for 3D-TV. In DIBR, stereoscopic images are created from monoscopic images and associated depth data. Since for most of the available video content sensor depth data are lacking, methods to create artificial depth data for video content have been developed. Yet artificial as well as sensor depth data may contain misalignments with respect to video data. Misaligned depth data are a source of artifacts observable in rendered 3D views. We show that by using an edge-based registration method, the spatial alignment of depth and video data can be improved, leading to an alleviation of the observed artifacts.
