SUMMARY:Computational Imaging for Realistic Appearance Modelling - Abhijee
 t Ghosh\, Imperial College London
DTSTART:20181121T161500Z
DTEND:20181121T170000Z
UID:TALK114835@talks.cam.ac.uk
CONTACT:Rafal Mantiuk
DESCRIPTION:In this talk\, I will present an overview of the research we h
 ave been conducting in the Realistic Graphics and Imaging group at Imperia
 l on measurement based appearance modelling for realistic computer graphic
 s. The talk will span techniques focusing both on standard geometric optic
 s based acquisition\, as well as imaging wave optical effects of surface r
 eflectance. In the standard geometric optics regime\, I will briefly descr
 ibe some of our work on acquiring the shape and reflectance of opaque spat
 ially varying planar material samples\, and acquiring transparent glass ob
 jects. I will then present some recent work on imaging wave optical effect
 s such as polarization for appearance acquisition in uncontrolled outdoor 
 environments\, and imaging surface diffraction to model the complex irides
 cence seen on manufactured materials such LCD screens and holographic samp
 les. The talk will conclude with a brief description of a multi-spectral L
 ight Stage apparatus that we have built at Imperial for facial and materia
 l appearance capture.\n\n\nBiography:\n\nAbhijeet Ghosh is a Senior Lectur
 er in the Department of Computing at Imperial College London\, where he le
 ads the Realistic Graphics and Imaging group and his current research inte
 rests include appearance modelling and computational photography/illuminat
 ion for graphics and vision. He currently holds an EPSRC Early Career Fell
 owship (2016-2021)\, and has recently held a Royal Society Wolfson Researc
 h Merit Award (2013-2017) in this area. Previously\, he was a Research Ass
 istant Professor at the USC Institute for Creative Technologies where he w
 orked on Light Stage based facial and appearance acquisition. Abhijeet com
 pleted his PhD in Computer Science from the University of British Columbia
  is 2007. His doctoral dissertation received the 2008 Alain Fournier award
  for the best Canadian PhD thesis in computer graphics. Abhijeet was a pro
 gram co-chair for Pacific Graphics 2018\, and is currently conference chai
 r for the ACM SIGGRAPH Conference on Visual Media Production (CVMP) 2018.\
