Optical Camera Communications

2016
Visible light communications (VLC) has been evolving at a much faster rate because of the development of high energy efficient white light emitting diodes (LED). For the first time, we see a unique device which offers triple functionalities of illumination, data communications and indoor localization, thus opening up the opportunities for applications ...

Practical design of Screen-to-Camera based Optical Camera Communication

2015 International Conference on Information Networking (ICOIN), 2015
This paper introduces the Optical Camera Communication (OCC) based on Computer Vision. The practical issues of implementation of the asynchronous communication based Screen-to-Camera are performed. The asynchronous scheme proposed by our previous work is modified to be simple, suitable and reliable in order to apply in case of heterogeneous frame rate ...

Invisible embedded techniques for optical camera communications

2017 International Conference on Information Networking (ICOIN), 2017
Optical camera communications (OCC) is a promising technology due to the development and commercialization of camera. Similarly with visible light communication (VLC), OCC will decode the signal from light source by invisibility or visibility. The invisibility technique for OCC is based on the over frequency response or less sensitive color of human ...

A survey of design and implementation for optical camera communication

Signal Processing: Image Communication, 2017
Visible Light Communication (VLC) has emerged as a promising technology for wireless communication owing to advantages such as bandwidth, license, coexistence and security. Additionally, it was officially standardized by IEEE 802.15.7 in 2011. However, it faces certain challenges that can be considered as grounds to develop a revised version.

Performance of rolling shutter and global shutter camera in optical camera communications

2015 International Conference on Information and Communication Technology Convergence (ICTC), 2015
Optical Camera Communication (OCC) is considered as an extension of IEEE 802.15.7 specification by same communication channel. Different with another technique, Optical Camera Communication used image sensor for receiver, so the characteristic of image sensor will effect on the operation and performance.

Applying NOMA to Undersampled Optical Camera Communication for Vehicular Communication

2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU), 2018
Visible Light Communications (VLC) is being developed as an alternative to radio frequency (RF) communication for vehicular applications. It has the advantages of high signal-to-noise ratio (SNR), limited interference due to line-of-sight transmission and dual use of existing hardware (LED lights and cameras) on most modern vehicles.

Camera and Inverse Camera System for Free-Space Optical Communications

Frontiers in Optics / Laser Science, 2018
We introduce an imaging-based transceiver for FSOC that enables precision beam steering over a wide field-of-regard using low-cost components with no moving parts. Passive beam steering provides dynamic beam-shaping and multiplexable communication.

Optical camera communications based invisible watermarking technique

2016 International Conference on Information Networking (ICOIN), 2016
Watermarking is well-known solution for copyright protection and safety certification in digital media. However for communication, it is a new issue which follows from the development of camera. In this paper we address the capability of invisible watermarking schemes for optical camera communication. By changing the invisible element of image, we will
