Short Bio
 
Vaggelis Spyrou
London, UK, January 2010		 Evaggelos Spyrou was born in Athens, Greece in 1979, but lived and finished high-school in Lamia, Greece. In September 1998 he begun his studies at the School of Electrical and Computers Engineering (ECE) of the National Technical University of Athens (NTUA) and received his diploma in November 2003, specializing in Telecommunications. He has been with Image, Video and Multimedia Systems Laboratory (IVML) from January 2004 to May 2010, working as a researcher and developer. In October 2004 he was accepted as a PhD candidate at the IVML of ECE-NTUA, in the field of Semantic Image and Video Analysis. His thesis, entitled "Semantic Search of Audiovisual Content using Knowledge", was completed in November 2009. From May 2010 to January 2011 he served his military service in the Department of Telecommunications of the Greek Ministry of Defense as an Analyst and Computer Programmer. He currently works as scientific associate with the Technological Educational Institute (T.E.I) of Lamia and as adjunct lecturer with the University of West Macedonia (UOWM). His current research interests lie in the areas of semantic multimedia analysis, indexing and retrieval, low-level feature extraction and modeling, visual context modeling, multimedia content representation, neural networks and intelligent systems.

Selected Works
Large-scale Image Retrieval using Scene Maps
State of the art data mining and image retrieval in community photo collections typically focus on popular subsets, e.g. images containing landmarks or associated to Wikipedia articles. We propose an image clustering scheme that, seen as vector quantization, compresses a large corpus of images by grouping visually consistent ones while providing a guaranteed distortion bound. This allows us...read more
Visual Context Modeling and Analysis
The idea behind the use of visual context information responds to the fact that not all human acts are relevant in all situations and this holds also when dealing with image analysis problems. Since visual context is a difficult notion to grasp and capture, in our research work we restrict it to the notion of ontological context... read more
High-Level Concepts in Multimedia
The motivation of this work is to tackle the problem of high-level concept detection within image and video documents using a globally annotated training set. The goal is to determine whether a concept exists within an image along with a degree of confidence and not its actual position. Since this approach begins with a coarse image segmentation, the high-level concepts that is able to tackle can be described as "materials" or "scenes". MPEG-7 color and texture features are locally extracted from coarsely segmented regions using an RSST variation. Using a significantly large set of images...read more
