Current Trends and Advances in Image Quality Assessment

Monday, 17th June, 10:15–11:00, Room A

Krzysztof Okarma is an Associate Professor and Head of Department of Signal Processing and Multimedia Engineering as well as the Dean of Faculty of Electrical Engineering at the West Pomeranian University of Technology, Szczecin (Szczecin, Poland). His research interests include computer vision, signal and image processing as well as applications of machine vision in automation, robotics and ITS. Currently, he focuses on image quality assessment, automatic quality evaluation of 3D prints as well as image binarization and binary image analysis. 

AImage quality assessment (IQA) is one of the constantly active are of research in computer vision. Starting form the idea of Universal Image Quality Index (UIQI), followed by well-known Structural Similarity (SSIM) and its numerous extensions and modifications, through Feature Similarity (FSIM) towards combined metrics using the multi-metric fusion approach, the development of quality assessment is still in progress. Nevertheless, regardless of new databases and the potential use of deep learning methods, some challenges remain still up-to-date. Some of the IQA metrics can also be used efficiently for alternative purposes, such as texture similarity, quality evaluation of 3D images and 3D printed surfaces as well as video quality assessment.


Vidmantas Tomkus (State research institute Center for Physical Sciences and Technology / Vilnius, Lithuania)

Quantum Key Distribution in 5G Networks

Monday, 17th June, 11:45-12:30, Room A

Vidmantas Tomkus received MSc degree in Physics from Vilnius University. From 1994 until present time has worked at different leading positions in Telecommunications and Satellite industry like CTO at Radio M-1, CEO at Dicto Citius and Arcus Novus UAB. 2009-2018 Vidmantas Tomkus served as a director of Lithuanian Aerospace Association and contributed to the co-operation of Lithuanian R&D institutions and SME's with European Space Agency and NASA. 2010 he was assigned as FP7 and Horizon 2020 Space expert from Lithuania. From 2015, Vidmantas Tomkus carries out the research in the State research institute Center for Physical Sciences and Technology in the field of High intensity laser radiation and its application in material science.

Emerging 5G networks will provide users with Enhanced Mobile Broadband, Massive connectivity of Internet of Things (IoT), Ultra High Reliability and Low latency integrating deeply heterogeneous systems. Separation of Control and User planes allows not only gradual transition from 4G networks to 5G Service-Oriented-Architecture, jointly operation of short-range, low-power and macro-cellular stations but also introduction of fundamentally new type of Quantum communications. Universal 5G-connectivity raise enhanced requirements of network security. In contrast to the current cryptography protocols based on mathematical algorithms, Quantum communications rely on quantum mechanical properties of photon’s states that cannot be unknowingly interrupted, cloned, or exposed during transmission. Quantum Key Distribution – first application of quantum connectivity deployed in metro fiber rings and over satellite for large-distance-communications. Basic principles of polarization encoding of qubits and development carried out in the Department of Laser Technologies of State research institute Center for Physical Sciences and Technology on Four-wave-mixing entangled photon source will be presented.
