Production of stereoscopic 3D visual information for entertainment applications such as 3D cinema, 3D-TV and video games, has seen a significant growth in recent years. The recent introduction of 3D-TV sets to the consumer market and the steady releases of stereoscopic 3D films in digital cinemas have greatly contributed to this explosion in stereoscopic 3D video production.
This explosion of content production, however, has not always taken into account the quality of experience of viewers. In the entertainment industry, much of the content that is produced comes from 2D-to-3D video conversion that tries to exploit the WOW factor of the depth information by trading-off depth quality and viewer comfort. Even content naturally captured in stereoscopic 3D format frequently have depth artifacts that results in viewers discomfort.
In this presentation I will introduce some of the issues that are related to the comfort of the viewer as well as the methods that we have devised to address them. Some examples will be presented in the form of 2D-to-3D video conversion inspired by the characteristics of the human visual system (HVS) which produces comfortable viewing experience, stereoscopic 3D video processing algorithms to enhance the depth quality of the acquired content, and the development of novel display methods to improve the perceived depth of the scenes while preserving a comfortable viewing experience for the end user. All these works take advantage of the availability of the depth information as depth maps and uses it to modify the depth structure of the scene for enhanced depth and image perception.
Prof. Vázquez, received the B. Eng. degree in Electronic Engineering with the highest honors in 1992 and the M.A.Sc. degree in Computer Sciences in 1997 from the Higher Polytechnic Institute José Antonio Echeverría (ISPJAE) in Havana, Cuba. He worked as a lecturer and assistant professor in the Telecommunications Department of ISPJAE from 1992 to 1997 when he joined the INRS-EMT in Montréal as a PhD candidate and recipient of an excellence scholarship from the Government of Québec. He received the Ph.D. degree in Telecommunications from the INRS-EMT, Montréal, Canada, in 2003.
Prof. Vázquez spent two years as a Post-Doctoral Fellow at the INRS-EMT until 2004 when he became Research Associate at Concordia University, Montréal, Canada. In August of 2005 he joined the Communications Research Centre Canada (CRC) as research scientist in the Advanced Video Systems group where he performed research related to the deployment of 3DTV systems. He is currently associate professor at the Software and IT Engineering Department of the École de technologie supérieure in Montréal since August 2013.
Dr. Vázquez is currently involved in 3D-TV, Multi-View video and 3D object extraction research. His research interests are in the broad areas of 3D visual information systems; 2D-to-3D video conversion; stereo and multi-view vision systems; 3D object extraction and reconstruction; image/video representation, sampling and interpolation; image and video coding; and motion/disparity/depth estimation and compensation. He is the author of numerous peer-reviewed journal and conference articles and co-recipient of the Scott Helt best paper award from the IEEE Broadcast Technology Society in 2011.
