Trilobite-inspired neural nanophotonic light-field camera with extreme depth-of-field
Nature Communications, 2022 A unique bifocal compound eye visual system found in the now extinct trilobite, Dalmanitina socialis, may enable them to be sensitive to the light-field information and simultaneously perceive both close and distant objects in the environment.

Proceedings of the British Machine Vision Conference 2014, 2014 A full view spherical camera exploits its extended field of view to map the complete environment onto a 2D image plane. Thus, with a single shot, it delivers a lot more information about the surroundings than one can gather with a normal perspective or plenoptic camera, which are commonly used in light field imaging.

Attosecond light field synthesis [PDF]
APL Photonics, 2021 The advancement of the ultrafast pulse shaping and waveform synthesis allowed to coherently control the atomic and electronic motions in matter. The temporal resolution of the waveform synthesis is inversely proportional to the broadening of its spectrum.

Unstructured Light Fields [PDF]
Computer Graphics Forum, 2012 AbstractWe present a system for interactively acquiring and rendering light fields using a hand‐held commodity camera. The main challenge we address is assisting a user in achieving good coverage of the 4D domain despite the challenges of hand‐held acquisition. We define coverage by bounding reprojection error between viewpoints, which accounts for all

Light Field Image Super-Resolution Using Deformable Convolution [PDF]
IEEE Transactions on Image Processing, 2020 Light field (LF) cameras can record scenes from multiple perspectives, and thus introduce beneficial angular information for image super-resolution (SR). However, it is challenging to incorporate angular information due to disparities among LF images. In

Attention-based Multi-Level Fusion Network for Light Field Depth Estimation
AAAI Conference on Artificial Intelligence, 2021 Depth estimation from Light Field (LF) images is a crucial basis for LF related applications. Since multiple views with abundant information are available, how to effectively fuse features of these views is a key point for accurate LF depth estimation ...

Learning Light Field Angular Super-Resolution via a Geometry-Aware Network [PDF]
AAAI Conference on Artificial Intelligence, 2020 The acquisition of light field images with high angular resolution is costly. Although many methods have been proposed to improve the angular resolution of a sparsely-sampled light field, they always focus on the light field with a small baseline, which ...
