Abstract

We introduce an algorithm for high-quality, interactive light field
rendering from only a small number of input images.

The algorithm bridges the gap between image warping and
interpolation from image databases, which represent the two major
approaches in image based rendering. By warping and blending only
necessary parts of the Lumigraph images, we are able to generate a
single view-corrected texture for every output frame at interactive
rates.

In contrast to previous light field rendering approaches, our
warping-based algorithm is able to fully exploit per-pixel depth
information in order to depth-correct the light field samples with
maximum accuracy.

The complexity of the proposed algorithm is independent of the
number of stored reference images and of the final screen
resolution. It performs with only small overhead and very few
visible artifacts. We demonstrate the visual fidelity as well as the
performance of our method through various examples.
