Short Biography
Dr.-Ing. Ekenel is the head of young investigator group on “Facial Image Processing and Analysis” at the Computer Science Department in Karlsruhe Institute of Technology (TH), Germany.
He received his B.Sc. and M.Sc. degrees in Electrical and Electronic engineering from Bogazici University in 2001 and 2003, respectively, and Ph.D. degree in Computer Science from the University of Karlsruhe (TH) in 2009.
His current research focuses on face processing and content-based image and video retrieval. He has been developing face recognition systems for smart environments, humanoid robots, and video analysis.
He had been the task leader for face recognition in the European Computers in the Human Interaction Loop (CHIL) project and he organized face recognition evaluations within the CLEAR 2006, 2007 international evaluation campaigns.
He has been responsible for face recognition in the German Humanoid Robots project. He is currently the task leader of face recognition in the French-German Quaero project.
He has received the EBF European Biometric Research Award in 2008 for his contributions to the field of face recognition.
His research on face recognition has been featured in the Quaero project and presented at the cover of the project’s homepage.
His research led more than 40 publications in international journals, conferences, and workshops.
In addition to the scientific work, many real-world systems have been developed based on his algorithm.
With these systems, he received the Best Demo Award at the IEEE International Conference on Automatic Face and Gesture Recognition in 2008.
Besides his research activities on face analysis, he has been also leading the video retrieval systems development efforts for the NIST TRECVID 2007, 2008, and 2009 evaluations.
