Computational imaging

JN Mait, GW Euliss, RA Athale - Advances in Optics and Photonics, 2018 - opg.optica.org
We review advances in Computational Imaging that have occurred since the mid-1990s. The
advent of highly integrated platforms, such as the smartphone, has made the linkage …

Deep learning for camera data acquisition, control, and image estimation

DJ Brady, L Fang, Z Ma - Advances in Optics and Photonics, 2020 - opg.optica.org
We review the impact of deep-learning technologies on camera architecture. The function of
a camera is first to capture visual information and second to form an image. Conventionally …

Light field blind motion deblurring

PP Srinivasan, R Ng… - Proceedings of the IEEE …, 2017 - openaccess.thecvf.com
We study the problem of deblurring light fields of general 3D scenes captured under 3D
camera motion and present both theoretical and practical contributions. By analyzing the …

Image translation for single-shot focal tomography

P Llull, X Yuan, L Carin, DJ Brady - Optica, 2015 - opg.optica.org
Focus and depth of field are conventionally addressed by adjusting longitudinal lens
position. More recently, combinations of deliberate blur and computational processing have …

Compressive tomography

DJ Brady, A Mrozack, K MacCabe… - Advances in Optics and …, 2015 - opg.optica.org
Compressive tomography consists of estimation of high-dimensional objects from lower
dimensional measurements. We review compressive tomography using radiation fields …

Near-invariant blur for depth and 2D motion via time-varying light field analysis

Y Bando, H Holtzman, R Raskar - ACM Transactions on Graphics (TOG), 2013 - dl.acm.org
Recently, several camera designs have been proposed for either making defocus blur
invariant to scene depth or making motion blur invariant to object motion. The benefit of such …

Feature detection performance based benchmarking of motion deblurring methods: applications to vision for legged robots

GK Gultekin, A Saranli - Image and Vision Computing, 2019 - Elsevier
Dexterous legged robots can move on variable terrain at high speeds. The locomotion of
these legged platforms on such terrain causes severe oscillations of the robot body …

Motion-invariant coding using a programmable aperture camera

T Sonoda, H Nagahara, R Taniguchi - IPSJ Transactions on …, 2014 - jstage.jst.go.jp
A fundamental problem in conventional photography is that movement of the camera or
captured object causes motion blur in the image. In this research, we propose coding motion …

Edge-preserving camera trajectories for improved optical character recognition on static scenes with text

R Katoch, J Ueda - IEEE Robotics and Automation Letters, 2019 - ieeexplore.ieee.org
Camera systems in fast motion suffer from the effects of motion blur, which degrades image
quality and can have a large impact on the performance of visual tasks. The degradation in …

Smart cameras

DJ Brady, M Hu, C Wang, X Yan, L Fang, Y Zhu… - arxiv preprint arxiv …, 2020 - arxiv.org
We review camera architecture in the age of artificial intelligence. Modern cameras use
physical components and software to capture, compress and display image data. Over the …
