Warping-based video retargeting for stereoscopic video

In this paper, a novel warping-based retargeting approach for stereoscopic video is proposed. It considers the three conflicting goals: preserving salient image content, avoiding flickering and maintaining consistency between the two views. The first step of the approach focuses on content-aware image resizing and considers image saliency, motion saliency, and depth saliency. In the second step, temporal coherence is preserved by tracking and optimizing deformed pathlines. The proposed algorithm maps the mesh from the left to the right view to guarantee consistency between the deformation of objects between the views. Users rated the quality of the adapted videos as good. In particular, distortions in the perceived depth are not noticeable, and the temporal stability is significantly higher compared to seam carving approaches.
