Short Bio

Dominic Ruefenacht received his B.Sc. and M.Sc. in communication systems with specialization in “Signals, Images and Interfaces” from the École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, in 2009 and 2011. He was an exchange student at the University of Waterloo, Ontario, Canada, and did his Master's thesis at Philips Consumer Lifestyle in Eindhoven, Netherlands, entitled “Stereoscopic High Dynamic Range Video”. He obtained his Ph.D. degree from UNSW Sydney, Australia, in 2017, where he was investigating “Novel Motion Anchoring Strategies for Wavelet-based Highly Scalable Video Compression”.
From 2011 to 2013, he was with the Image and Visual Representation Group (IVRG) at EPFL as a research engineer, where he was working on computational photography problems, with emphasis on near-infrared imaging.
He currently holds a post-doctoral position at UNSW Sydney, working on next-generation video compression systems. His research interests are in computational photography and highly scalable and accessible video compression, with a focus on temporal scalability.

Hierarchical Motion Field Anchoring for Highly Scalable Video Coding
We propose to use ‘‘physical’’ motion rather than block motion, as commonly used in video coding standards. Together with estimated motion discontinuities, this allows to flip the motion field anchoring to the target frames, which has a number of key benefits over the traditional motion anchoring.

Motion-Centric Temporal Frame Interpolation
A novel approach for temporal frame interpolation (TFI) which only uses motion information and estimated motion discontinuities in the frame interpolation process. During the motion mapping process, we obtain high-quality disocclusion masks, which are useful to guide the bidirectional frame interpolation process.
