Title: "Challenges to picture quality in video content workflows"

Abstract: Video is responsible for more than 80% of internet traffic and there are more video creating devices in the world than people. Generating this video, editing it and moving it around consumes energy and compute resources.  Since 2015 we now produce more pixels per frame and at a higher bit depth than ever before. This trend is set to get worse with the launch of new AR/VR headsets. In this talk we present the basics of the modern streaming media pipeline and recent developments in DSP/ML techniques for maintaining picture quality. We highlight the need for a more considered approach to video manipulation which balances resource consumption with performance. 

Biography: Anil Kokaram graduated in 1993 with the PhD in Signal processing from the Cambridge University Engineering Department, UK. He is now Professor and Chair of Electronics at Trinity College Dublin, Ireland. From 2011-2017 he was the lead of the Media Algorithms Team at YouTube/Google. Before that he founded a media DSP group at Trinity www.sigmedia.tv working in the broad areas of DSP for Video Processing, Bayesian Inference and motion estimation. He has published over 200 refereed papers in these areas. He was a former Associate Editor of the IEEE Transactions on Video Technology and IEEE Transactions on Image Processing and currently serves as Senior Area Editor. He was founder of a company (GreenParrotPictures) producing video enhancement software that was acquired by Google in 2011. In 2007 he was honoured with a Science and Engineering Academy Award from the American Academy of Motion Picture Arts and Sciences for his work in video processing for post-production applications.
