Abstract: S-3DTV (Stereoscopic-3DTV), HDR (High Dynamic range), 4K are recent considered technologies to improve the viewer experience. Nevertheless, such technologies are really useful only if properly tuned to increase the Quality of Experience (QoE). For instance, S-3DTV (stereoscopic-3DTV) is supposed to provide enhanced depth perception to viewer but might affect other factors of user experience. Subjective assessment is the most direct way to assess quality of experience (QoE). However, conventional assessment methods are not sufficient to evaluate the QoE of S-3DTV. This talk aims to review the challenge of QoE assessment through use cases related to S-3DTV and HDR. Methodologies to evaluate QoE with observers will be discussed, including environment conditions, scales and display characterization.
CV: Patrick LE CALLET is full professor at Ecole polytechnique de l’université de Nantes (Engineer School) in the Electrical Engineering and the Computer Science department where. Since 2006, he is the head of the Image and VideoCommunication lab at CNRS IRCCyN, a group of more than 35 researchers. He is mostly engaged in research dealing with the application of human vision modeling in image and video processing. His current centers of interest are 3D image and video quality assessment, watermarking techniques and visual attention modeling and applications. He is co-author of more than 150 publications and communications and co-inventor of 13 international patents on these topics. He has coordinated and is currently managing for IRCCyN several National or European collaborative research programs representing grants of more than 2,5 million euros. He is serving in VQEG (Video Quality Expert Group) where is co-chairing the „HDR Group“ and „3DTV“ activities. He is currently serving as associate editor for IEEE transactions on Circuit System and Video Technology, SPIE Journal of Electronic Imaging and SPRINGER EURASIP Journal on Image and Video Processing.
