2D/3D video conversion method based on piece-wise structure from motion

  • 摘要: 为了缓解3D片源的不足,设计了一种分段化结构重建方法为视频2D/3D转换提供深度线索.采用分层提取的方式,将视频基于内容分解为子序列,在每个子序列中建立优化准则选择出处于非退化状态的关键帧,并以此为基础提出了分段化结构重建框架,利用改进的耦合自标定算法重构出每个子序列对应的离散3D结构信息,从而获取视频的深度线索.实验结果表明,该方法通过分段化后的局部优化,不仅使结构化重建能够有效处理多场景下的连续镜头,还加快了转换的效率,能够稳定、高效地获取深度信息,适用于视频2D/3D转换.
