MoRSE: Deep Learning-based Arm Gesture Recognition for Search and Rescue Operations

no code implementations15 Oct 2022 Panagiotis Kasnesis, Christos Chatzigeorgiou, Dimitrios G. Kogias, Charalampos Z. Patrikakis, Harris V. Georgiou, Aspasia Tzeletopoulou

In this paper, we present a smartwatch-based application, which utilizes a Deep Learning (DL) model, to recognize a set of predefined arm gestures, maps them into Morse code via vibrations enabling remote communication amongst first responders.

Wind models and cross-site interpolation for the refugee reception islands in Greece

no code implementations25 Jul 2017 Harris V. Georgiou

In this study, the wind data series from five locations in Aegean Sea islands, the most active `hotspots' in terms of refugee influx during the Oct/2015 - Jan/2016 period, are investigated.

Identification of refugee influx patterns in Greece via model-theoretic analysis of daily arrivals

no code implementations9 May 2016 Harris V. Georgiou

This work is such an attempt for a systemic analysis of the refugee influx in Greece, aiming at (a) the statistical and signal-level characterization of the smuggling networks and (b) the formulation and preliminary assessment of such models for predictive purposes, i. e., as the basis of such an early warning-alerting protocol.
