Light Fields Reloaded

Digital images play an essential role in our life. Advanced imaging systems, image processing methods, and visualization techniques are today fundamental to many professions. Medical imaging is certainly a good example. However, when mapping complex (possibly multidimensional) data to 2D, information is lost. What if the notion of digital images would change once and forever? 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. I will introduce the fundamentals of light fields, explain how light fields are captured, processed, and displayed, and present several applications of light-field technology in various application domains, such as microscopy, sensors, and aerial scanning.

Oliver Bimber became head of the Institute of Computer Graphics at Johannes Kepler University Linz. He co-authored the book "Displays: Fundamentals and Applications" (2011, 2016) with Rolf R. Hainich and the book "Spatial Augmented Reality" (2005) 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 (2006) that was presented together with the Turing award. Bimber's research interests include visual computing and optics in the context of next-generation display and imaging technologies. Besides work, he likes flying and spending as much time as possible with his wife, Melanie, and his dog, Leni.
