Abstract:
Multiview displays are characterized by a multitude of parameters, such as spatial resolution, brightness, 3D-crosstalk, and so forth, which individually and in combination influence the visual quality of 3D scenes. These parameters are specified by values precisely measured by optical means. However, it is difficult for an average consumer or content producer to compare the visual quality of two displays or to judge whether given 3D content is suitable for a certain display using only this set of parameter values. In this talk, we will describe a quality-measurement methodology that aims to measure the visibility of structural distortions introduced by a multiview display by using a number of test signals with different frequency content and apparent depth. We use these measurements to derive what we call display passband for signals at different disparity levels. The passband determines the frequency components for which the intended signal is predominantly visible with respect to the distortion introduced by the display. Additionally, we look into a method to determine the approximate effective resolution of a display for signals with a given apparent depth. The result of the measurements can be used to compare the perceived visual quality of different multiview displays.

 

CV:
Robert Bregović received the Dipl.Ing. and M.Sc. degrees in electrical engineering from the Faculty of Electrical Engineering and Computing, University of Zagreb, Zagreb, Croatia, in 1994 and 1998, respectively, and the Dr. Tech. degree in information technology from the Tampere University of Technology, Tampere, Finland, in 2003. From 1994 to 1998, he was an Assistant at the Department of Electronic Systems and Information Processing, Faculty of Electrical Engineering and Computing, University of Zagreb. Since 1999 he is with the Department of Signal Processing, Tampere University of Technology, where he is currently working as a Senior Researcher. In 2005 and 2006 he was a visiting Research Fellow at Nanyang Technological University, Singapore, and in 2013 he was a Senior Researcher at HolografikaKft. Budapest. His research interests are in the design of filters and filter banks, multi-dimensional signal analysis and light field sensing, processing and display.
