Per-Object Image Warping with Layered Impostors

Image warping is desirable in the context of image-based rendering because it increases the set of viewpoints for which a single image can be used. This paper proposes a method for image warping with adaptive accuracy compatible with current texture-mapping hardware. It is based on the observation that pixels at similar depth move in a similar way during warping. The method also generates approximate depth values at each pixel so that polygonal and image-based rendering can be applied in a mixed fashion.
