Learning-based view synthesis for light field cameras [PDF]
ACM Transactions on Graphics, 2016 With the introduction of consumer light field cameras, light field imaging has recently become widespread. However, there is an inherent trade-off between the angular and spatial resolution, and thus, these cameras often sparsely sample in either spatial

Event-Based Motion Segmentation by Motion Compensation [PDF]
, 2019 In contrast to traditional cameras, whose pixels have a common exposure time, event-based cameras are novel bio-inspired sensors whose pixels work independently and asynchronously output intensity changes (called "events"), with microsecond resolution ...

Dynamic obstacle avoidance for quadrotors with event cameras
Science Robotics, 2020 Micro-aerial vehicles dodge fast-moving objects using only onboard sensing and computation. Today’s autonomous drones have reaction times of tens of milliseconds, which is not enough for navigating fast in complex dynamic environments.

Video to Events: Recycling Video Datasets for Event Cameras [PDF]
Computer Vision and Pattern Recognition, 2019 Event cameras are novel sensors that output brightness changes in the form of a stream of asynchronous "events" instead of intensity frames. They offer significant advantages with respect to conventional cameras: high dynamic range (HDR), high temporal ...

A Unifying Contrast Maximization Framework for Event Cameras, with Applications to Motion, Depth, and Optical Flow Estimation [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018 We present a unifying framework to solve several computer vision problems with event cameras: motion, depth and optical flow estimation. The main idea of our framework is to find the point trajectories on the image plane that are best aligned with the ...

A unilateral 3D indoor positioning system employing optical camera communications
IET Optoelectronics, 2023 This article investigates the use of a visible light positioning system in an indoor environment to provide a three dimensional (3D) high‐accuracy solution. The proposed system leveraged the use of a single light‐emitting diode and an image sensor at the

Automatic calibration of multiple cameras and lidars for autonomous vehicles
Компьютерная оптика, 2021 Autonomous navigation of unmanned vehicles (UVs) is currently one of the most interesting scientific and technical problems, and this is even more true for UVs moving across rough terrain.

BLAST Autonomous Daytime Star Cameras [PDF]
, 2006 We have developed two redundant daytime star cameras to provide the fine pointing solution for the balloon-borne submillimeter telescope, BLAST. The cameras are capable of providing a reconstructed pointing solution with an absolute accuracy < 5 ...

Camera Calibration Through Camera Projection Loss
ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2022 Camera calibration is a necessity in various tasks including 3D reconstruction, hand-eye coordination for a robotic interaction, autonomous driving, etc. In this work we propose a novel method to predict extrinsic (baseline, pitch, and translation), intrinsic (focal length and principal point offset) parameters using an image pair.
