CoRR, 2019 Most computer vision systems and computational photography systems are visible light based which is a small fraction of the electromagnetic (EM) spectrum. In recent years radio frequency (RF) hardware has become more widely available, for example, many cars are equipped with a RADAR, and almost every home has a WiFi device.

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.

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.

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 ...
