A 2D —3D Video Conversion Method Based on Layer Optimization and Integration

To alleviate the shortage of 3D media sources,a 2D —3D video conversion method is proposed in this work which is based on layered optimization and integration on the preliminary results from structure from motion(SFM).The main steps include: Firstly,depth cue of scene sparse structures is obtained by a segment-wise SFM approach.Secondly,an extended interactive segmentation algorithm based on GrabCut is used to extract different object layers,and then dense depth generation and optimization are carried out in each layer independently to enhance local visual stereoscopic quality.Thirdly,depth of different layers are integrated considering the visual saliency features to complete 2D —3D video conversion.Experiments show that the proposed method can yield more visually satisfactory results.
