Title: Bit Rate Control for Multi-view plus Depth Video

Multi-view Video-plus-Depth (MVD) sequences are required to provide an enhanced immersive user experience. This is because it provides good rendering quality and flexible processing capabilities, supports wide angle 3D and stereoscopic displays, and allows the rendering of a continuum of output views with high image quality and low complexity through the use of depth-image-based rendering (DIBR) techniques.
A key element in any 3D video encoder is the rate control mechanism which allows the compressed video stream to be sent on bandwidth-limited networks. Some works reported in literature simply assign 20% of the available bit rate to the depth data, which is not optimal. Thus, the best texture-depth rate allocation needs to be predicted during encoding to ensure the best quality of the synthesized views at the decoder. In this talk we will discuss a rate control method for MVD which is based on the characteristics of the depth data.
Carl James Debono received his B.Eng.(Hons.) degree in Electrical Engineering from the University of Malta, Malta, in 1997 and the Ph.D. degree in Electronics and Computer Engineering from the University of Pavia, Italy, in 2000.
Between 1997 and 2001 he was employed as a Research Engineer in the area of Integrated Circuit Design with the Department of Microelectronics at the University of Malta. In 2000 he was also engaged as a Research Associate with Texas A&M University, Texas. In 2001 he was appointed Lecturer with the Department of Communications and Computer Engineering at the University of Malta and is now an Associate Professor. He is currently the Deputy Dean of the Faculty of ICT at the University of Malta.
Prof. Debono is a senior member of the IEEE and served as chair of the IEEE Malta Section between 2007 and 2010 and vice-chair between 2011 and 2012. He was the IEEE Region 8 Conference Coordination sub-committee chair for 2011 and 2012 and Vice-chair of Technical Activities for IEEE Region 8 for 2013 and 2014. His research interests are in resilient multimedia transmission, multi-view video coding, wireless systems design and applications, and modeling of communication systems.
