SegFlow: Joint Learning for Video Object Segmentation and Optical Flow

, 2017
This paper proposes an end-to-end trainable network, SegFlow, for simultaneously predicting pixel-wise object segmentation and optical flow in videos. The proposed SegFlow has two branches where useful information of object segmentation and optical flow ...

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 ...

Wide Field-of-View Air-to-Water Rolling Shutter-Based Optical Camera Communication (OCC) Using CUDA Deep-Neural-Network Long-Short-Term-Memory (CuDNNLSTM)

Applied Sciences
Nowadays, underwater activities are becoming more and more important. As the number of underwater sensing devices grows rapidly, the amount of bandwidth needed also increases very quickly. Apart from underwater communication, direct communication across the water–air interface is also highly desirable.

Water-to-air unmanned aerial vehicle (UAV) based rolling shutter optical camera communication (OCC) system with gated recurrent unit neural network (GRU-NN)

Optics Express
Underwater sensors and autonomous underwater vehicles (AUVs) are widely adopted in oceanic research activities. As the number of underwater sensors and AUVs is growing quickly, the bandwidth requirements are increasing accordingly. In this work, we put forward and demonstrate a large field-of-view (FOV) water-to-air unmanned aerial vehicle (UAV) based ...
