Ahmet Tekalp#
A short laudatio by Erol Gelenbe#
Ahmet Tekalp is a highly cited researcher (over 130 journal papers, 3000+ citations according to Google-scholar with h-index=44), an inventor (8 US patents granted, 4 pending), and renowned educator (selected as Distinguished Lecturer by IEEE Signal Processing Society). He is an advocate and leader of inter-disciplinary research across the signal/image processing, computer vision/graphics, telecommunications, and the Internet research communities.
He has authored key work in the areas of: (i) image-blur identification and restoration by 2D Kalman filtering, (ii) super-resolution from video, (iii) simultaneous motion estimation and segmentation, (iv) 2D mesh animation compression, (v) automatic annotation and summarization of soccer videos, (vi) multi-modal modelling of head/facial gestures and speech prosody, and (vii) 3D media streaming over the Internet. During his PhD, he made foundational contributions to statistical image-blur modelling and identification As a professor, he was the first to apply the method of projection onto convex sets to space-varying image restoration and super-resolution from video (more than 500 citations) He was also the first to propose a Bayesian framework for simultaneous motion estimation and segmentation. His 2D mesh based animation compression method has received wide attention from both video compression and computer graphics communities (adopted to MPEG-4). He was the first to publish a completely automatic procedure to annotate and summarize broadcast soccer videos (more than 340 citations). Most recently, he has participated in two EC FP6 Network of Excellence projects, SIMILAR and 3DTV, and is the Coordinator of an EC FP7 Network of Excellence, 3DMEDIA. His work under the SIMILAR project resulted in development of multi-modal models of dependency between head/face gestures of speakers and prosody of their speech.
As an inventor, two of his works have been listed among the most cited patents by MIT Technology Review in 1999 and 2006. The first of these technologies, 2D mesh animation compression (US 5,654,771) has been adopted in the MPEG-4 International Standard. The other is automated annotation and summarization of soccer videos (US 2004/0130567). He has also contributed technology to the MPEG-7 International Standard.
As an educator, he wrote the first textbook on Digital Video Processing in 1995, which has been cited 1195 times (Google-scholar) and was translated into Chinese and Korean. In 1998, he was selected as a Distinguished Lecturer by IEEE Signal Processing Society. Prof. Tekalp holds several teaching awards. He has been involved in leadership positions at IEEE, including the Chair of IEEE Technical Committee on Image and Multidimensional Signal Processing (1996-1998), founding member of IEEE Technical Committee on Multimedia Signal Processing (1998-2002), and Chair of IEEE Rochester Section (1994-1996). Prof. Tekalp has strong ties with industry. He has been a consultant to Eastman Kodak, Xerox, and Siemens Research. He is currently in the Board of ARGELA, Istanbul, Turkey.
He also plays important service roles in terms of editorial duties on leading journals and conference program committees. After serving as an Associate Editor in IEEE Trans. on Signal Processing and IEEE Trans. on Image Processing, since 1999 Prof. Tekalp has been the Editor-in-Chief of EURASIP journal Signal Processing: Image Communication published by Elsevier. He has been involved in the organization of the three main conferences in signal/image processing, IEEE International Conf. on Acoustics, Speech and Signal Processing (ICASSP), IEEE International Conf. on Image Processing (ICIP), and European Signal Processing Conference (EURASIP). He has been the Technical Program Chair for ICASSP 2000, General Chair for ICIP 2002 and Technical Program Chair for EURASIP2005. Additionally, he has taken an active role in the organization of many other conferences and workshops in the field. Most recently, he was the Keynote Speaker in the Immersive Telecommunications Conference (IMMERSCOM 2009) organized at UC Berkeley.
