Abstract: Light field cameras, also called plenoptic cameras, capture a field of light rays traveling in space, i.e., the intensity and direction of light rays. This is contrary to conventional still-picture cameras that acquire the aggregated… read more here.

DOI: 10.1109/tci.2019.2911856
Abstract: In standard photography, vignetting is considered mainly as a radiometric effect because it results in a darkening of the edges of the captured image. In this paper, we demonstrate that for light field cameras, vignetting… read more here.

DOI: 10.1109/tpami.2018.2864617
Abstract: Light field cameras can capture both spatial and angular information of light rays, enabling 3D reconstruction by a single exposure. The geometry of 3D reconstruction is affected by intrinsic parameters of a light field camera… read more here.

DOI: 10.1364/ao.465129
Abstract: The accuracy of reconstructing depth maps or performing digital refocusing in light field cameras depends largely on how well the spatial and angular samples of light rays can be obtained. Ray sample errors induced by… read more here.
