Ljubomir Jovanov was born in Pančevo, Yugoslavia, on July 13, 1975. He received dipl.ing. degree in Electrical Engineering and mr. ing. degree in Telecommunications, in 2000 and 2005 respectively, both from the University of Novi Sad, Serbia. In 2006 he joined the Department of Telecommunications and Information Processing of Ghent University, Belgium as a PhD student. His main research interests are image, video and 3D restoration, image analysis and processing of multimedia data. In 2011 he defended his PhD thesis entitled "Advanced Restoration Techniques for 3D Images and Video".
