    Abstract(s): 

    Digital images play an essential role in our life. Advanced imaging systems, image processing methods, and visualization techniques are today fundamental to many professions. However, when mapping complex (possibly multidimensional) data to 2D, information is lost. What if instead of capturing, storing, processing and displaying only a single color per pixel, each pixel would consist of individual colors for each emitting direction? Digital images would no longer be two-dimensional matrices but four-dimensional ones (storing spatial information in two dimensions, and directional information in the other two dimensions). This is called a light field. In the past twenty years, light-field technology has mainly focused on photography applications, and failed to attract a critical mass of consumers. I will explain what the future potential of this technology might be in other domains, such as microscopy, thin-film sensors, and aerial scanning.

    Speaker Bio(s): 

    Oliver Bimber is the head of the Institute of Computer Graphics at the Johannes Kepler University Linz, Austria.  He achieved his PhD in 2002 from Darmstadt University of Technology, Germany in Engineering.  He co-authored the book "Displays: Fundamentals and Applications" with Rolf R. Hainich and the book "Spatial Augmented Reality" with Ramesh Raskar (MIT). From 2005 until 2015, he served on the editorial board of the IEEE Computer Magazine. The VIOSO GmbH was founded in his group in 2005. He and his students received several awards for their research and inventions, and have won scientific competitions, such as the ACM Siggraph Student Research Competition, and the ACM Student Research Competition Grand Final which was presented together with the Turing award. His graduates are holding leading positions in academia, such as Stanford University or ETH Zürich, and Industry, such as Facebook, Mendeley (founder), DAQRI, Snap Inc., or Audi Research. Bimber's research interests include visual computing and optics in the context of next-generation display and imaging technologies.
