个人简介
Ioannis Katsavounidis (Senior Member, IEEE) is currently part of the Video Infrastructure Team, Meta, leading technical efforts in improving video quality and quality of experience across all video products. Before joining Meta, he spent three and half years with Netflix, contributing to the development and popularization of VMAF, Netflix’s open-source video quality metrics, and inventing the dynamic optimizer, a shot-based perceptual video quality optimization framework that brought significant bitrate savings across the whole streaming spectrum and awarded Netflix two technical Emmys in 2020. He was a Professor for eight years with the Electrical and Computer Engineering Department, University of Thessaly, Greece, teaching video compression, signal processing, and information theory. He was one of the co-founders of Cidana, a mobile multimedia software company in Shanghai, China. He was the Director of Software for Advanced Video Codecs with InterVideo, the makers of WinDVD, the most popular SW DVD player, in the early 2000’s, and he has also spent four years working in high-energy experimental physics in Italy. He is one of the co-chairs of the statistical analysis methods (SAM) and no-reference metrics (NORM) groups with the Video Quality Experts Group (VQEG). He is actively involved within the Aliance for Open Media (AOM) as the Co-Chair of the Software Implementation Working Group (SWIG). He has over 150 publications, including 50 patents. His research interests lie in video coding, quality of experience, adaptive streaming, and energy efficient HW/SW multimedia processing.
