The authors describe a technique that transforms a video from a hand-held video camera so that it appears as if it were taken with a directed camera motion. The method adjusts the video to appear as if it were taken from nearby viewpoints, allowing 3D camera movements to be simulated. By aiming only for perceptual plausibility, rather than accurate reconstruction, they are able to develop algorithms that can effectively recreate dynamic scenes from a single source video. The technique first recovers the original 3D camera motion and a sparse set of 3D, static scene points using an off-the-shelf structure-from motion system. Then, a desired camera path is computed either automatically (e.g., By fitting a linear or quadratic path) or interactively.
