Abstract
We present a novel approach to recording and computing panorama light fields. In contrast to previous methods that estimate panorama light fields from focal stacks or naive multi-perspective image stitching, our approach is the first that processes ray entries directly and does not require depth reconstruction or matching of image features. Arbitrarily complex scenes can therefore be captured while preserving correct occlusion boundaries, anisotropic reflections, refractions, and other light effects that go beyond diffuse reflections of Lambertian surfaces.

Coded exposure HDR light-field video recording
Capturing exposure sequences to compute high dynamic range HDR images causes motion blur in cases of camera movement. This also applies to light-field cameras: frames rendered from multiple blurred HDR light-field perspectives are also blurred. While ...
Multiple light field rendering
GRAPHITE '03: Proceedings of the 1st international conference on Computer graphics and interactive techniques in Australasia and South East AsiaA light field is a 4D function describing the radiance across a boundary between the volume containing a scene, and the disjoint volume in which the eyepoint may be placed. Light field rendering is the process of rendering novel views of a scene ...
