Scalable Motion-Aware Panoramic Videos

The work presents a method for obtaining perceptually natural panoramic videos, that is, videos composed of wide-angle frames, where straight lines and object shapes are preserved. The shape preservation for moving objects has a special treatment in order to avoid unpleasant temporal artifacts. The problem is geometrically modeled for the case of a fixed omnidirectional camera, and a solution by optimization is presented. Our optimization works per-frame, which makes the proposed method scalable and practical for arbitrarily long scenes. Results show the potential of this technique as a way to provide more information in a movie, and reveals new possibilities for the art of film making.
