Lead in the Chrome Media Group at Google, Mountain View CA. He continues to hold his Professorship with the Department of Electronic Engineering, Trinity College Dublin and is a Fellow of the College. He is the author of over 100 refereed papers in various conferences and journals over the years. His research interests include the general area of digital video processing and algorithms for stereoscopic quality improvement and video processing in the life sciences. He is best known for his work in automated motion picture restoration.
Prof. Kokaram was an Associate Editor of IEEE Transactions in Image Processing from 2002 to 2007. He was a recipient of an Academy Award alongside colleagues at The Foundry (a visual effects software manufacturer in London) for his contribution to a range of visual algorithms in 2007.

Research Assistants, interns, and other positions
Hugh Denman was not the first SigMedian to start a PhD under Prof. Kokaram, nor was he the first to finish, but of those who finished, he was the first to start (but not vice-versa). His research ranged over analysis of broadcast snooker footage, adaptive edit-point re-synchronization for retiming of dance video, shot change detection, and video segmentation. He was a member of Prof. Kokaram’s “Green Parrot Pictures” enterprise, which led to a stint at Google working within the YouTube transcoder team. He then worked in algorithmic music video generation for a few years, and is now a developer in the HFT industry. He has maintained links with SigMedia throughout, most recently assisting in the delivery of course 4C16 “Machine Learning with Media Applications”.
