Optical Camera Communication Application using Display Modulation

2020 International Conference on Artificial Intelligence in Information and Communication (ICAIIC), 2020
QR code is commercialized as a matrix barcode and widely used in many applications. However, there are still many drawbacks of using QR code when the demand of data transferring amount is increasing, while remaining the communication reliability and small code size.

SNR Analysis for Non-Line-of-Sight MIMO Optical Camera Communications

International Symposium on Communication Systems, Networks and Digital Signal Processing
In this paper, we experimentally demonstrate the interference analysis of a non-line-of-sight (NLOS) multiple-input multiple-output (MIMO)-based optical camera communications (OCC) link. We propose an NLOS MIMO-OCC using two organic light emitting diodes

Non-Blind Image Restoration Technique in Screen–to–Camera based Optical Camera Communications

2024 7th International Balkan Conference on Communications and Networking (BalkanCom)
This paper presents a novel blur restoration technique specialized for smartphone-to-camera based communication (screen to camera, S2C) system. The key technique is to avoid the repeated scanning of the transmitted data and to lower the amount of data ...

Synchronous time multiplexing for non-line-of-sight multiple-input multiple-output optical camera communications.

Optics Letters
In typical multiple-input multiple-output (MIMO) optical camera communication (OCC) systems, the spatial correlation of MIMO channels is large. Optical signals between light sources can easily interfere with each other, negatively impacting the overall ...

Towards Autonomous Optical Camera Communications: Light Source Localisation Using Deep Learning

Electronics
This research significantly improves the link reliability and robustness of optical camera communications (OCC) by leveraging deep learning for light source modulation filtering, reflection filtering, and precise light source localisation. By using image

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

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 ...

Optical camera communications for platooning applications

2023
Platooning is a technology that corresponds to all the coordinated movements of a collection of vehicles, or, in the case of mobile robotics, to all the coordinated movements of a collection of mobile robots. It brings several advantages to driving, such as, improved safety, accurate speed control, lower CO2 emission rates, and higher energy efficiency.
