Light fields and Lumigraphs have recently received a lot of
attention in the computer graphics community, since they allow to
render scenes from a database of images very efficiently. While
warping based approaches are still too slow to achieve truly
interactive frame rates, Lumigraph rendering can easily achieve tens of
frames per second in full screen on a contemporary graphics
workstation. On the down side, high resolution Lumighraphs require large
amounts of storage and are expensive to acquire, while low
resolutions yield low quality images with lots of blurring.
In this paper, we propose to refine an initial sparse Lumigraph
through the use of a specialized warping algorithm. This algorithm
increases the resolution of the Lumigraph by inserting new views,
which can then be used to generate higher quality images through
normal quadri-linear interpolation. This way, storage requirements and
acquisition costs remain low, but image quality is increased
drastically.
