We describe a theoretical framework for reversibly modulating 4D light fields using an
attenuating mask in the optical path of a lens based camera. Based on this framework, we …

We propose a new type of lensless camera enabling light-field imaging for focusing after
image capture and show its feasibilities with some prototyping. The camera basically …

This paper describes a novel approach to partially reconstruct high-resolution 4D light fields
from a stack of differently focused photographs taken with a fixed camera. First, a focus map …

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 …

We propose a non-permanent add-on that enables plenoptic imaging with standard
cameras. Our design is based on a physical copying mechanism that multiplies a sensor …

We demonstrate a compact, easy-to-build computational camera for single-shot three-
dimensional (3D) imaging. Our lensless system consists solely of a diffuser placed in front of …

Light field cameras capture full spatio-angular information of the light field, and enable many
novel photographic and scientific applications. It is often stated that there is a fundamental …

This paper presents a camera that samples the 4D light field on its sensor in a single
photographic exposure. This is achieved by inserting a microlens array between the sensor …

The emergent field of computational photography is proving that, by coupling generalized
imaging optics with software processing, the quality and flexibility of imaging systems can be …

We propose a learning-based framework for acquiring a light field through a coded aperture
camera. Acquiring a light field is a challenging task due to the amount of data. To make the …
