Capturing high-dimensional (HD) data is a long-term challenge in signal processing and
related fields. Snapshot compressive imaging (SCI) uses a 2D detector to capture HD (≥ …

Multidimensional optical imaging has seen remarkable growth in the past decade. Rather
than measuring only the two-dimensional spatial distribution of light, as in conventional …

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 …

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 …

Coded aperture is a promising approach for capturing the 4-D light field (LF), in which the 4-
D data are compressively modulated into 2-D coded measurements that are further decoded …

Current light field (LF) cameras provide low spatial resolution and limited depth-of-field
(DOF) control when compared to traditional digital SLR (DSLR) cameras. We show that a …

Compressive imaging using coded apertures (CA) is a powerful technique that can be used
to recover depth, light fields, hyperspectral images and other quantities from a single …

Recent imaging technologies are rapidly evolving for sampling richer and more immersive
representations of the 3D world. One of the emerging technologies is light field (LF) cameras …

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 …

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 …
