Uğur Güdükbay is a professor at Department of Computer Engineering, Bilkent University, Ankara, Turkey. He received his Ph.D. degree in Computer Engineering and Information Science from Bilkent University, Ankara, Turkey, in 1994. Then, he conducted research as a postdoctoral fellow at Human Modeling and Simulation Laboratory, University of Pennsylvania, Philadelphia, Pennsylvania.
Dr. Uğur Güdükbay is doing research in the in the fields of Computer Graphics and Multimedia Databases and has research contributions in these areas. In the area of Computer Graphics, he and his colleagues developed techniques for the visualization of complex geometric environments, such as terrain height fields and urban models. They developed a hybrid terrain representation that allows modeling of volumetric terrain features such as caves, overhangs, cliffs, and arches, that cannot be modeled using surface terrain representations, such as height fields. They expanded algorithms for stereoscopic view-dependent visualization of terrain height fields. They proposed a slice-wise representation for buildings, which is a data structure that stores buildings using axis-aligned slices. They exploited this representation to develop an occlusion culling algorithm for urban areas. Slicewise representation brings significant computational and storage gains. He also have contributions in various aspects of crowd simulation, such as impact of personality models on crowd behavior, path planning and modeling crowd behavior in emergency situations. He also involved in research activities for 3D scene representation technologies for 3D Television.
In the area of multimedia databases and content-based retrieval, he and his colleagues developed an MPEG-7 compliant video database system. The system allows text-based semantic, color, texture, shape, location, motion and spatio-temporal querying of video databases. They also have contributions to content-based retrieval of historical document archives.
He was the principal investigator and researcher for various projects funded by European Council (EC) and Turkish Scientific and Technical Research Council (TUBITAK). He worked as a researcher in Multimedia Understanding through Semantics, Computation and Learning (MUSCLE) Network of Excellence Project supported by EC Sixth Framework Program. He worked as a researcher and workpackage leader in Integrated Three-Dimensional Television - Capture, Transmission and Display (3DTV) Network of Excellence Project supported by EC Sixth Framework Program. His project about the visualization of urban environments received Career Award from TUBITAK.
He is a senior member of ACM and IEEE. He served as the Chair of IEEE Computer Society Turkey Chapter between 2004 and 2006. He co-chaired three conferences: i) Capture, Transmission and Display of 3D Video (3DTV-CON'11), Antalya, Turkey, May 2011, ii) Capture, Transmission and Display of 3D Video (3DTV-CON'08), Istanbul, Turkey, 28-30 May 2008 and iii) 13th International Symposium on Computer and Information Sciences (ISCIS'98), Antalya, Turkey, October 1998. He was the guest editor of a journal special issue (Special Issue on Advances in Three Dimensional Television and Video, Signal Processing: Image Communication, Vol. 24, Nos. 1-2 January, 2009.) He is on the Editorial Board of Signal, Image and Video Processing Journal (Springer). He served on the Program Committees of 1st IEEE Workshop on Modeling, Simulation and Visual Analysis of Large Crowds (MSVLC), November 7, 2011, Barcelona, Spain and the Pattern Recognition and Crowd Analysis Workshop (PRCA 2012) at ICPR 2012, Tsukuba, Japan. He also took conference duties for many prestigious conferences, such as ACM SIGGRAPH International Resources Committee Member, ACM SIGCHI Conference Reviewer. He works as an expert for evaluating projects and project proposals for EC.
He published 57 peer-reviewed journal articles, 55 refereed conference papers, 4 book chapters and edited three conference proceedings and a journal special issue. He published in journals including, ACM Journal on Computing and Cultural Heritage, IEEE Transactions on Visualization and Computer Graphics, IEEE Transactions on Circuits and Systems for Video Technology, IEEE Transactions on Image Processing, IEEE Computer Graphics and Applications, IEEE Multimedia, Computer-Aided Design, Computer & Graphics, Graphical Models, Computer Vision and Image Understanding, Multimedia Tools and Applications, Journal of Visualization, Signal Processing: Image Communication, Image and Vision Computing, Journal of Molecular Graphics and Modelling, The Visual Computer and Leonardo.
