Title: Generative Models for Image/Video Super-resolution and Compression
Time: 14:30 pm, May 20, 2023 (Saturday)
Abstract:
It is common practice to use regressive models that minimize a measure of distortion for image/video super resolution (SR) and variational auto-encoders (VAE) to minimize rate distortion loss for image/video compression tasks. Although generative models, such as GANs and flow models, have been previously used for perceptual image/video SR and compression, they have limitations such as convergence and stability of training. Recenty, diffusion models have become very popular for different image/video synthesis applications. This talk discusses possible use of pixel space and feature space (stable) diffusion models for perceptual image/video SR and compression tasks and compares their advantages an d disadvantage vs. stable GAN model training approaches.
Personal Introduction:
A. Murat Tekalp (Fellow, IEEE) received the Ph.D. degree in electrical, computer, and systems engineering from Rensselaer Polytechnic Institute (RPI), Troy, NY, USA, in 1984. He was with Eastman Kodak Company, Rochester, New York, from 1984 to 1987, and with the University of Rochester, Rochester, New York, from 1987 to 2005, where he was promoted to Distinguished University Professor. He is currently a Professor with Koc University, Istanbul, Turkey. He served as the Dean of Engineering between 2010 and 2013. His research interests are in digital image and video processing, including video compression and streaming, video networking, multi-view and 3-D video processing, and deep learning for image video processing and compression. He has been elected a member of Turkish Academy of Sciences and Academia Europaea. He served as an Associate Editor for the IEEE Transactions on Signal Processing (1990–1992) and IEEE Transactions on Image Processing (1994–1996). He was the Editor-in-Chief for the EURASIP journal Signal Processing: Image Communication published by Elsevier between 1999 and 2010. He was on the Editorial Board for the IEEE Signal Processing Magazine (2007–2010) and the Proceedings of the IEEE (2014–2020). He chaired the IEEE Signal Processing Society Technical Committee on Image and Multidimensional Signal Processing (January 1996–December 1997). He was appointed as the General Chair of IEEE International Conference on Image Processing (ICIP), Rochester, NY, USA, in 2002 and the Technical Program Co-Chair for IEEE ICIP 2020 and ICIP 2024. He served in the European Research Council (ERC) Advanced Grant Panels (2009–2015) and Starting Grant Panel in 2021. He is currently on the Editorial Board of Wiley-IEEE Press. He has authored the Prentice Hall book Digital Video Processing (1995), a completely rewritten second edition of which is published in 2015.
