Abstract
With the popularity of 3D films, the conversion of existing 2D videos to 3D videos has attracted a wide interest in 3D content production. In this paper, we present an efficient approach for 2D to 3D video conversion based on structure from motion (SFM). The key contributions include a piece-wise SFM approach and a novel nonlinear depth warping considering the characteristics of stereoscopic 3D. The dense depth maps are generated and further refined with color segmentation. Experiments show that the proposed approach can yield more visually satisfactory results.
