Wireless Software Synchronization of Multiple Distributed Cameras
, 2019 We present a method for precisely time-synchronizing the capture of image sequences from a collection of smartphone cameras connected over WiFi. Our method is entirely software-based, has only modest hardware requirements, and achieves an accuracy of ...

Laser &Photonics Reviews, EarlyView.This paper demonstrates a snapshot 5D and modality‐switchable lensless camera (Diffuser‐mCam), which can encode 2D intensity, multi‐spectral, polarization, and time information into a monochromatic raw data, and subsequently decode it using the compressed sensing algorithm at the sampling rate of 2.5% per channel.

Unsupervised Odometry and Depth Learning for Endoscopic Capsule Robots
, 2018 In the last decade, many medical companies and research groups have tried to convert passive capsule endoscopes as an emerging and minimally invasive diagnostic technology into actively steerable endoscopic capsule robots which will provide more ...

Simulation of Rolling Shutter Acquisition in Optical Camera Communications [PDF]
2019 15th International Conference on Telecommunications (ConTEL), 2019 The rolling shutter (RS) acquisition mechanism performed by the majority of the digital cameras included in portable devices has been exploited to make receivers for visible light communications (VLC). They are able to decode signals of frequencies higher than the frame rate of the camera, which is a limitation when using global shutter sensors.

Region-of-Interest Signaling Vehicular System Using Optical Camera Communications
IEEE Photonics Journal, 2017 This technical paper introduces an optical camera communication system for vehicles. The purpose of the communication system incorporated into car (using existing light-emitting diode (LED) lights and ordinary cameras) is to add region-of-interest ...

Efficient Continuous-Time SLAM for 3D Lidar-Based Online Mapping
, 2018 Modern 3D laser-range scanners have a high data rate, making online simultaneous localization and mapping (SLAM) computationally challenging. Recursive state estimation techniques are efficient but commit to a state estimate immediately after a new scan ...

The Journal of American Culture, EarlyView.ABSTRACT This article examines the use of promotional interviews (“promos”) in American professional wrestling of the 1980s. I argue that promos introduced a vocal modality into a form of sports entertainment that, as Roland Barthes ([1957] 1972) showed in Mythologies, had always been dominated by visual spectacle. I then undertake a focused linguistic

Secure Mobile-Phone Based Visible Light Communications With Different Noise-Ratio Light-Panel
IEEE Photonics Journal, 2018 We propose and demonstrate a visible light communication (VLC) system using a light-panel and a mobile-phone camera. We also propose the rolling-shutter-effect (RSE) pattern synchronization and demodulation algorithms. By using our developed mobile-phone

USB-NeRF: Unrolling Shutter Bundle Adjusted Neural Radiance Fields
, 2023 Neural Radiance Fields (NeRF) has received much attention recently due to its impressive capability to represent 3D scene and synthesize novel view images. Existing works usually assume that the input images are captured by a global shutter camera. Thus,
