Light field imaging has emerged as a technology allowing to capture richer visual
information from our world. As opposed to traditional photography, which captures a 2D …

Underwater optical images are usually influenced by low lighting, high turbidity scattering
and wavelength absorption. To solve these issues, a great deal of work has been performed …

This paper introduces an algorithm that accurately estimates depth maps using a lenslet
light field camera. The proposed algorithm estimates the multi-view stereo correspondences …

Light-field cameras have recently become available to the consumer market. An array of
micro-lenses captures enough information that one can refocus images after acquisition, as …

Light field photography has gained a significant research interest in the last two decades;
today, commercial light field cameras are widely available. Nevertheless, most existing …

This paper describes a method for scene reconstruction of complex, detailed environments
from 3D light fields. Densely sampled light fields in the order of 109 light rays allow us to …

Light-field cameras are now used in consumer and industrial applications. Recent papers
and products have demonstrated practical depth recovery algorithms from a passive single …

We present a novel method for the geometric calibration of micro-lens-based light field
cameras. Accurate geometric calibration is the basis of various applications. Instead of using …

We report an imaging scheme, termed aperture-scanning Fourier ptychography, for 3D
refocusing and super-resolution macroscopic imaging. The reported scheme scans an …

The core of any optical imaging system is a photodetector. Whether it is film or a
semiconductor chip in a camera, or indeed the retina in an eye, conventional photodetectors …
