Papavassiliou Vassilis

Areas of interest

  • Digital Image Processing
  • Pattern Recognition
  • Document Image Analysis
  • Optical Character Recognition with emphasis on handwriting

Vassilis Papavassiliou received the Diploma degree in the Electrical and Computer Engineering from the National Technical University of Athens (NTUA), Greece, in 1998. The title of his thesis was “Development of a Speech Recognition System for Educational Software”. The results of this thesis were incorporated in the “Filoglossia” educational multimedia product. He also holds a M.Sc. degree in Language Technology graduating from NTUA & National & Kapodistrian University of Athens in 2000. The subject of his M.Sc. thesis focused on a statistical approach of the literary style with applications to author identification. In 2010, he obtained his Ph.D. degree at NTUA on handwritten document image analysis under the supervision of Professor Carayannis. During pursing his Ph.D., he participated in teaching of the “Digital Signal Processing” course at the School of Electrical and Computer Engineering – N.T.U.A.
He has been associated with the Institute for Language and Speech Processing (ILSP / R.C. “Athena”) since 1998. He has worked on several educational multimedia projects as a software engineer. The more recent ones are “A knight in the castle of letters“, “ECDL Tests” (7CD-ROMs), «ECDL-Advanced Tests» (4 CD-ROMs), “Trilingual Term Dictionary” and “Nea Logomatheia”. He has also participated, as a research assistant, in the research projects “Panoptis” (a system for detection of artificial text in videos), “SAMS” (an optical handwritten recognition system of mathematical symbols) and “PENED 2003 – Applications of Pattern Recognition on Language technology”. Currently he focuses on applied research in computational linguistics and development of two systems for acquiring monolingual and bilingual data from the web in the context of the research project “PANACEA”.
His research interests involve digital image processing with emphasis on document image analysis and machine learning and pattern recognition with applications to handwritten character recognition. The results of his basic and applied research are incorporated in commercial products or laboratory prototypes.
He is a member of the National Technical Chamber of Greece (TEE) since 1998.
