    Abstract
  • To alleviate the shortage of 3D media sources, a piece-wise structure from motion method was designed to provide depth cues for the 2D/3D video conversion. Videos were decomposed into subsequences of different scenes and key frames of non-degenerate were extracted in each subsequence with optimization criteria. On this basis, a piece-wise structure from motion framework was proposed and depth cues of scene sparse structures were obtained through an improved coupling self-calibration algorithm. Experimental results show that by local optimization after video segmentation, the proposed method can handle video shot containing multiple scenes based on structure from motion, and improve the efficiency of conversion effectively. Those mean the proposed method is suitable for the 2D/3D video conversion.
