Light Field Image Coding Based on Hybrid Data Representation [PDF]
, 2022 This paper proposes a novel efficient light field coding approach based on a hybrid data representation. Current state-of-the-art light field coding solutions either operate on micro-images or sub-aperture images.

Tying Knots in Light Fields [PDF]
Physical Review Letters, 2013 We construct a new family of null solutions to Maxwell's equations in free space whose field lines encode all torus knots and links. The evolution of these null fields, analogous to a compressible flow along the Poynting vector that is both geodesic and shear-free, preserves the topology of the knots and links.

Light field moment imaging [PDF]
Optics Letters, 2013 We introduce a novel imaging technique called light field moment imaging (LMI) that uses the continuity equation to extract the first angular moments of a light field. We use these moments to construct perspective views of a scene. Examples of LMI in photography and microscopy are presented.

Angularly Consistent Light Field Video Interpolation
, 2020 International audienceIn this paper, we address the problem of temporal interpolation of sparsely sampled video light fields using dense scene flows. Given light fields at two time instants, the goal is to interpolate an intermediate light field to form ...

Compressive Light Field Sensing [PDF]
IEEE Transactions on Image Processing, 2012 We propose a novel design for light field image acquisition based on compressive sensing principles. By placing a randomly coded mask at the aperture of a camera, incoherent measurements of the light passing through different parts of the lens are encoded in the captured images.

Plasmonic metafiber for all-fiber Q-switched cylindrical vector lasers
Nanophotonics, 2023 Metafibers, by integrating metasurface at the optical fiber tip, are emerging as the significant optical coupling platforms for nanophotonics and fiber-optic communities. Here, we propose a plasmonic metafiber for converting the fundamental mode to first-

A Multispectral Light Field Dataset and Framework for Light Field Deep Learning [PDF]
IEEE Access, 2020 Deep learning undoubtedly has had a huge impact on the computer vision community in recent years. In light field imaging, machine learning-based applications have significantly outperformed their conventional counterparts. Furthermore, multi- and hyperspectral light fields have shown promising results in light field-related applications such as ...

Depth estimation and validation of plenoptic light field camera
, 2023 A light field (LF) camera can record both the spatial and directional information of light rays in a three-dimensional (3D) scene. This is different from traditional photography, which sums up all the light rays to record their intensity and discard the ...
