Marinos Vlachos, PhD student, Research Assistant
Marinos Vlachos is a researcher in the Photogrammetric Vision Lab. He holds an M.Sc. in Geomatics Engineering and Photogrammetry from University of Stuttgart. He also holds a bachelor’s degree in Surveying Engineering and Geomatics, from the Cyprus University of Technology. During his studies he earned a distinction for his Diploma Thesis entitled “Dense Image Matching for High Precision Digital Surface Model Accuracy through UAV flight patterns”, and published a paper entitled “Investigating Influence of Unmanned Aerial Vehicle Flight Patterns in Multi-Stereo View DSM Accuracy” that was presented in the SPIE Optical Metrology 2015 conference in Munich Germany. Currently he is working on his Master Thesis as he completes his studies at University of Stuttgart. Furthermore, his research often deals with the creation of accurate 3D models through Structure from Motion both from aerial and underwater imagery as well as the integration of various cameras (RGB and MS) with UAV platforms.
ALUMNI
Dr. Elias Frentzos, Senior Research Fellow
Dr. Elias Frentzos, received his Diploma (1997) in Civil Engineering and MSc (2002) in Geoinformatics, both from the National Technical University of Athens, Greece. He also holds a PhD from the Department of Informatics of the University of Piraeus (UniPi), where he has also conducted his postdoc research being a scholar of the Greek State’s Scholarships Foundation. He has participated in several national and European research projects. He has published more than 25 papers with more than 700 citations, in scientific journals such as KAIS, Geoinformatica, and IEEE Transactions on Knowledge and Data Engineering (TKDE), and in conferences such as ACM SIGMOD and IEEE ICDE. He has been awarded by IEEE with the best application paper award in ICDM 2009 for the paper “Clustering Trajectories of Moving Objects in an Uncertain World”. He has served as a reviewer for ACM TODS, IEEE TKDE, VLDBJ and other scientific journals. Currently he is an associate of the Cyprus Technical University (CUT) and UniPi. He is the founder of Geonoesis, a Greek SME involved in the field of Software development, Geographic Information Systems and other engineering services. He has developed several commercial GIS-based applications, and participated as technical manager in several GIS projects, including, the project of the Hellenic Cadastral, and the project “Networks GIS” for the Hellenic Telecommunications Organization. His research interests include spatial and spatio-temporal databases, location-based services and geographical information systems. Dr. Frentzos is currently an external collaborator of the Lab.
Dr. Eleni Savvidou, Research Assistant
Eleni has granted a MEng at Geospatial Environmental Information Management and MSc at Environmental Systems Engineering from UCL, in 2009 and 2010 respectively. Her MSc dissertation project was titled "Oprimising Hydro-economic Systems: Application to California’s Sacramento Valley”. She is most interested in the use of Geographical Information Systems (G.I.S) and remote sensing techniques for solving water resource management problems
Since June 2011 is a PhD candidate in CUT. Her research focuses on automated drainage network extraction and how can this have an impact in flood risk mapping, using tools such as GIS (SWAT/Hydrogeios) and UAV mapping.
