Motion-Compensated Orthogonal Video Transforms

Abstract:
In 1989, Torbjorn Kronander observed that techniques known at that time for 3D subband coding of image sequences do not use motion compensation. Knowing the importance of motion compensation for efficient video coding, he proposed a method for invertible motion fields. Unfortunately, motion compensation is, in general, not invertible and subsequent research addressed the problem of motion-compensated subband coding.In this talk, we review the basic concepts of video compression, stress advantages and disadvantages of popular compression schemes, and present a new class of motion-compensated orthogonal video transforms. This class offers strictly orthonormal subbands while permitting general motion compensation.Bio:
Markus Flierl is Visiting Assistant Professor at the Max Planck Center for Visual Computing and Communication at Stanford University. He received the Doctorate in Engineering from Friedrich Alexander University, Germany, in 2003. From 2003 to 2005, he has been a senior researcher at the Swiss Federal Institute of Technology Lausanne, Switzerland. He has authored the book 'Video Coding with Superimposed Motion-Compensated Signals: Applications to H.264 and Beyond.' He has been named the recipient of the 2007 VCIP Young Investigator Award. His research interests include visual communication networks and video representations.Host: Professor Antonio Ortega, x02320, ortega@sipi.usc.edu
