DESCRIPTION:Our visual systems constantly gather and process data from the
  complex four-dimensional world we are immersed in. Streams of light\, aft
 er intricate interactions within the environment\, are reorganised as sequ
 ences of images by optical systems such as our eyes or cameras. We subcons
 ciously interpret the pictures as two-dimensional snapshots of our world -
 - a slice in time and a projection down from three-dimensional space. I wi
 ll present my recent work on many aspects related to the synthesis of phot
 o-realistic images given virtual descriptions of the scene as well as came
 ra. I will argue that the notion of photo-realism is coupled with the ever
 -increasing sophistication of camera technology.\n\nIn this context\, I wi
 ll discuss empirical tools to analyse three problems of practical photo-re
 alistic depiction: simulation\, abstraction and representation. First\, I 
 will talk about a frequency domain analysis of light fields and demonstrat
 e its utility in efficient Monte Carlo integration. Next\, I will introduc
 e empirical mode decomposition as a tool for detail abstraction. Finally\,
  I will briefly present work in progress\, on using multidimensional scali
 ng for alternate image representations.\n\nBio:\n\nKartic Subr is a Newton
  fellow and honorary research associate at University College London. Prev
 iously\, Kartic was a post-doctoral researcher and Marie-Curie fellow at I
 NRIA-Grenoble\, France. He received the doctoral degree for his work on sa
 mpling strategies for Monte Carlo integration\, at the University of Calif
 ornia\, Irvine under the late Prof. James Arvo who was a pioneer of light 
 transport methods in computer graphics.
