This 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 that ensures temporal coherence. Energies describing these properties are obtained for the case of a fixed omni-directional camera, and an optimization procedure is presented. Our optimization works per-frame, which makes the method scalable for arbitrarily long scenes.
