Using Pixel-per-bit Neural Network for Two Rolling Shutter Patterns Decoding in Optical Camera Communication (OCC)

2021 30th Wireless and Optical Communications Conference (WOCC), 2021
Optical wireless communication (OWC) has received increasing attention recently. One application of OWC uses image sensor as optical receiver, which is known as optical camera communication (OCC). Rolling shutter mode in OCC allows data rate higher than the camera frame-rate operation.

Z-Score Averaging Neural Network and Background Content Removal for High Performance Rolling Shutter based Optical Camera Communication (OCC)

Optical Fiber Communication Conference (OFC) 2021, 2021
We propose and demonstrate using Z-score averaging neural-network (Z-NN) and background-content-removal (BCR) to mitigate the inter-symbol-interference (ISI) in camera-communication (OCC). 950-bit/s over 3-m free-space transmission is achieved.

Display Light Panel and Rolling Shutter Image Sensor Based Optical Camera Communication (OCC) Using Frame-Averaging Background Removal and Neural Network

Journal of Lightwave Technology, 2021
Optical wireless communication (OWC) has emerged as a complementary or alternative technology to the radio-frequency (RF) communication. OWC based on image sensor, which is also called optical camera communication (OCC) has attracted much attention from industrial and academic societies. Here, we discuss several recent OCC technologies.

OCC Protocol for connected LEDs in Optical Camera Communication Networks

2018 Tenth International Conference on Ubiquitous and Future Networks (ICUFN), 2018
Nowadays, and Internet of Lights (IoL) can be used to help a variety of lights in home, building, factory, city, and so on. The achievement of wireless communication technologies have brought convenience and amazing services to users. The hybrid use of wireless technologies in a system is not a novel idea, however, in this paper, we introduce the ...

An indoor positioning method in a concert hall using optical camera communication (OCC) technology

2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017
Recent smart devices offer technologies that can measure indoor as well as outdoor locations. In the case of outdoor positioning, a global positioning system (GPS) is generally used. There is a limit to the method of using the GPS signal for indoor positioning.

Markov Models for predicting the Internet of Behaviour (IoB) of tourists: Optical Camera Communications (OCC) as a localization tool for indoor touristic scenarios

2023
This work proposes a simulation tool of a system aimed to predict the movements of tourists in an indoor scenario. It is based on a visible light positioning (VLP) system using LED lamps and an App in the user's mobile phone. VLP offers a dual illumination-location solution and provides highly accurate indoor positioning data of the user, able to feed ...
