Abstract

Three-dimensional TV is now closer than ever to become a reality for consumers providing a complete life-like image experience. Recent advances in autostereoscopic displays have resulted in improved 3D viewing experience, wider viewing angles, no need for special glasses and support for multiple viewers. However, due to their content formatting requirements (2D + depth), liveaction content is much more difficult to create. In this paper a new content generation approach for autostereoscopic 3DTV is proposed, by integrating a state-of-the-art MRF-based depth estimation method with additional pre- and post-processing steps, such as rectification, colour segmentation as well as decomposition of the scene in foreground and background depth maps. Experimental results with different stereo sequences show the great potential of the proposed method.
