Predavanje: "Light Field Image Processing"

Abstract

Light field imaging is becoming increasingly popular thanks to recent advances in acquisition devices. By capturing light rays emitted along different directions, light fields yield a rich description of the scene, enabling post-capture processing that can be appealing for a variety of applications. However, the huge volume of high-dimensional light field data is an obvious issue for storage, transmission but also for fast processing. Acquisition devices designed so far to capture light fields come with some technological limitations that translate into trade-offs between angular and spatial resolution. This talk will review fundamentals in light field imaging, the related plenoptic function, the main capturing devices and will present fundamental problems in light field image processing.

Short Biography

Christine Guillemot is currently Director of Research at INRIA (Institut National de Recherche en Informatique et Automatique) in France. She holds a PhD degree from ENST (Ecole Nationale Supérieure des Telecommunications) Paris (1992). From 1985 to 1997, she has been with France Telecom working in the areas of image and video compression for multimedia and digital television. From 1990 to mid 1991, she has worked as visiting scientist at Bellcore Bell Communication research in the USA. Her research interests are signal and image processing, and in particular 2D and 3D image and video coding, joint source and channel coding for video transmission over the Internet and over wireless networks, and distributed source coding. She has served as Associate Editor for IEEE Transactions on Image Processing (from 2000 to 2003 and from 2014 to 2016), for IEEE Transactions on Circuits and Systems for Video Technology (from 2004 to 2006), IEEE Transactions On Signal Processing (2007-2009), for the Eurasip journal on image communication (2010-2016), and member of the IEEE Journal on Selected Topics in Signal Processing (2013-2016). She is IEEE fellow since January 2013.
