Single-shot coded-aperture optical imaging physically captures a code-aperture-modulated
optical signal in one exposure and then recovers the scene via computational image …

In typical cameras the optical system is designed first; once it is fixed, the parameters in the
image processing algorithm are tuned to get good image reproduction. In contrast to this …

Abstract High-dynamic-range (HDR) imaging is crucial for many applications. Yet, acquiring
HDR images with a single shot remains a challenging problem. Whereas modern deep …

A unique bifocal compound eye visual system found in the now extinct trilobite, Dalmanitina
socialis, may enable them to be sensitive to the light-field information and simultaneously …

Portable light field (LF) cameras have demonstrated capabilities beyond conventional
cameras. In a single snapshot, they enable digital image refocusing and 3D reconstruction …

In this paper, we propose the first end-to-end convolutional neural network (CNN)
architecture, Defocus Map Estimation Network (DMENet), for spatially varying defocus map …

The classical approach to depth from defocus uses two images taken with circular apertures
of different sizes. We show in this paper that the use of a circular aperture severely restricts …

We present a method that takes as input a single dual-pixel image, and simultaneously
estimates the image's defocus map---the amount of defocus blur at each pixel---and …

The classical approach to depth from defocus (DFD) uses lenses with circular apertures for
image capturing. We show in this paper that the use of a circular aperture severely restricts …

A computational camera uses a combination of optics and processing to produce images
that cannot be captured with traditional cameras. In the last decade, computational imaging …
