Talk Abstract:<\/strong><\/b>\u00a0Light fields are a collection of rays emanating from a 3D scene at various directions, that when properly captured provides a means of projecting depth and parallax cues on 3D displays. However due to the limited aperture size and the constrained spatial-angular sampling of many light field capture systems (e.g. plenoptic cameras), the displayed light fields provide only a narrow viewing zone in which parallax views can be supported. In addition, the autostereoscopic displaying devices may be of unmatched spatio-angular resolution (e.g. integral display) or of different architecture (e.g. multi-panel display) as opposed to the capturing plenoptic system which requires careful engineering between the capture and display stages. This talk presents an efficient light field retargeting pipeline for integral and multi-panel displays which provides us with a controllable enhanced parallax content. This is accomplished by slicing the captured light fields according to their depth content, boosting the parallax, and merging these slices with data filling. In integral displays, the synthesized views are simply resampled and reordered to create elemental images that beneath a lenslet array can collectively create multi-view rendering. For multi-panel displays, additional processing steps are needed to achieve seamless transition over different depth panels and viewing angles where displayed views are synthesized and aligned dynamically according to the position of the viewer. The retargeting technique is simulated and verified experimentally on actual integral and multi-panel displays<\/p>\n

Speaker’s Biography:<\/strong><\/b>\u00a0Basel Salahieh is a research scientist at Intel Labs working on computational imaging, light field processing, autostereoscopic displays, and virtual reality. He received his BS in electrical engineering from the University of Aleppo \u2013 Syria in 2007, his first MS degree in electrical engineering from University of Oklahoma in 2010, his second MS degree in optical sciences and PhD degree in electrical and computer engineering from the University of Arizona in 2015. He has published more than 15 papers in international conferences and journals and more than 5 pending patents. In addition to his role at intel, Basel is currently serving as the president of the Syrian Society for Scientific Research organization<\/p>\n
