This extended session took place at IBC2023 on Saturday 16 September, at the RAI Amsterdam. There were four authors presenting current research spanning a range of important video processing topics – encoding, super-resolution and sustainability. These five papers are available to download via the links below.

This Technical Papers session includes: 

  • A tutorial review and performance comparison into the art of machine learning based super-resolution – with both impressive results and useful insight
  • A unique and detailed subjective assessment of current solutions to an old and challenging problem – maintaining creative intent when encoding film grain
  • A demonstration of the clear performance benefits using the new VVC coding tool “reference picture resampling”, can bring when adaptive streaming
  • A means to significantly reduce the power consumption in HDR displays by employing machine learnt “region of interest” detection and a just-noticeable difference approach to luminosity adaptation.

Here, the authors used an objective assessment technique across a selection of different display types resulting in a useful reduction in power consumption. This session is further supported by another VVC encoding paper, this one focused on 8K-60fps real-time encoding and provides comparative compression performance and discussion on computational resource requirements.

Nelson Francisco, Principal Video Compression Engineer  - MediaKind


Nelson Francisco

Nelson Francisco is a Principal Video Compression Engineer at MediaKind, formerly Ericsson Media Solutions. He joined Ericsson in 2013 to work in the development of core compression and video pre-processing algorithms, having contributed along the years to both hardware and software platforms in the company’s live and on-demand video delivery solutions lineup. His research currently focuses on media processing and delivery applications of AI and ML, ranging from automatic encoder configuration and codec optimizations, all the way to emerging topics such as super-resolution or video semantics analysis.  

Between 2007 and 2013, he collaborated with the Portuguese Telecommunication Institute (IT) on several government funded projects on the Image and Video compression domains, while being an Assistant Professor at the Polytechnic Institute of Leiria (Portugal). In 2013, he joined the Multimedia Telecommunication group of the Poznan University of Technology (Poland) as a visitant Post-doc researcher under the European Cooperation in Science and Technology programme, where he focused his work in multi-view video processing.  

He received a MSc degree in Electronics Engineering from the University of Trás-os-Montes e Alto Douro (Portugal) in 2008, and a PhD in Signal Processing from the Federal University of Rio de Janeiro (Brazil) in 2012, with his thesis receiving an honourable mention in the CAPES awards distinguishing the best Engineering thesis defended in Brazil in that year. 

Benjamin Bross, Head of Video Coding Systems - Fraunhofer HHI


Benjamin Bross

Benjamin Bross (Fraunhofer HHI) received the Dipl.-Ing. degree in electrical engineering from RWTH Aachen University, Aachen, Germany, in 2008. In 2009, he joined the Fraunhofer Institute for Telecommunications – Heinrich Hertz Institute, Berlin, Germany, where he is currently heading the Video Coding Systems group at the Video Communication & Applications Department and in 2011, he became a part-time lecturer at the HTW University of Applied Sciences Berlin. Since 2010, Benjamin is very actively involved in the ITU-T VCEG | ISO/IEC MPEG video coding standardisation processes as a technical contributor and chief editor of the High Efficiency Video Coding (HEVC) standard and the new Versatile Video Coding (VVC) standard. In addition to his involvement in standardisation, his group is developing standard-compliant software implementations. This includes the development of an HEVC live software encoder that is currently deployed in broadcast for HD and UHD TV channels and most recently, the open and optimized VVC software implementations VVenC and VVdeC. 

Gosala Kulupana, Lead R&D Engineer - BBC R&D


Gosala Kulupana

Gosala Kulupana received the B.Sc. Engineering degree (First Class) in electronic and telecommunications engineering from the University of Moratuwa, Sri Lanka, in 2011 and the PhD degree from Centre for Vision, Speech and Signal Processing (CVSSP), University of Surrey in 2017. His PhD was around application of error correction algorithms for High Efficiency Video Coding (HEVC) video transmission. Following his PhD, he worked as a Research Fellow at CVSSSP, University of Surrey where he contributed to two international research projects. In 2018 he joined the video compression team at BBC R&D as a researcher engineer. Currently he works as a Lead R&D Engineer in the video compression team. While working for the BBC, he contributed towards the development of Versatile Video Coding (VVC) standard and lead a Innovate-UK project SEQUOIA. Gosala is an author of several IEEE conference papers and journal publications and holds few patents for video compression related technologies. One of his research papers on fast VVC encoding algorithms received the Top-10 paper award in the Picture Coding Symposium (PCS) 2021. His current research interests include video compression, video streaming, High Dynamic Range (HDR) videos, and picture quality assessment.
