Unstructured light field rendering using on-the-fly focus measurement

This paper introduces a novel image-based rendering method which uses inputs from unstructured cameras and synthesizes free-viewpoint images of high quality. Our method uses a set of depth layers in order to deal with scenes with large depth ranges. To each pixel on the synthesized image, the optimal depth layer is assigned automatically based on the on-the-fly focus measurement algorithm that we propose. We implemented this method efficiently on a PC and achieved nearly interactive frame-rates.
