SUMMARY:Conférences GRSV : Vision Realistic Rendering
DESCRIPTION:Les conférences du Groupe de la recherche en sciences de la vi
 sion de l'École d'optométrie avec l'appui de Nikon Canadan présentent u
 ne conférence intitulée :Vision Realistic RenderingConférencier : Prof

 TRACT Vision-realistic rendering (VRR) is the computer generation of synth
 etic images to simulate a subject's vision\, by incorporating the characte
 ristics of a particular individual’s entire optical system. Using measur
 ed aberration data\, VRR modifies input images to simulate the appearance 
 of the scene for the individual patient. Each input image can be a photogr
 aph\, synthetic image created by computer\, frame from a video\, or standa
 rd Snellen acuity eye chart -- as long as there is accompanying depth info
 rmation. An eye chart is very revealing\, since it shows what the patient 
 would see during an eye examination\, and provides an accurate picture of 
 his or her vision. VRR provides images and videos of simulated vision to e
 nable a patient's eye doctor to see the specific visual anomalies of the p
 atient. In addition to blur\, VRR could reveal to the doctor the multiple 
 images or distortions present in the patient's vision that would not other
 wise be apparent from standard visual acuity measurements. VRR could educa
 te medical students as well as patients about the particular visual effect
 s of certain vision disorders (such as keratoconus and monocular diplopia)
  by enabling them to view images and videos that are generated using the o
 ptics of various eye conditions. By measuring PRK/LASIK patients pre- and 
 post-op\, VRR could provide doctors with extensive\, objective\, informati
 on about a patient's vision before and after surgery. Potential candiates 
 contemplating surgery could see simulations of their predicted vision and 
 of various possible visual anomalies that could arise from the surgery\, s
 uch as glare at night. The current protocol\, where patients sign a consen
 t form that can be difficult for a layperson to understand fully\, could b
 e supplemented by the viewing of a computer-generated video of simulated v
 ision showing the possible visual problems that could be engendered by the
  surgery. Recent work on correcting visual aberrations with computational 
 light field displays will also be briefly introduced.   BIOGRAPHYBrian A
 . Barsky is Professor of Computer Science and Vision Science\, and Affilia
 te Professor of Optometry\, at the University of California at Berkeley\, 
 USA. He is also a member of the Joint Graduate Group in Bioengineering\, a
 n interdisciplinary and inter-campus program\, between UC Berkeley and UC 
 San Francisco\, and a Fellow of the American Academy of Optometry (F.A.A.O
 .). Professor Barsky has co-authored technical articles in the broad areas
  of computer aided geometric design and modeling\, interactive three-dimen
 sional computer graphics\, visualization in scientific computing\, compute
 r aided cornea modeling and visualization\, medical imaging\, and virtual 
 environments for surgical simulation. He is also a co-author of the book A
 n Introduction to Splines for Use in Computer Graphics and Geometric Model
 ing\, co-editor of the book Making Them Move: Mechanics\, Control\, and An
 imation of Articulated Figures\, and author of the book Computer Graphics 
 and Geometric Modeling Using Beta-splines. Professor Barsky also held visi
 ting positions in numerous universities of European and Asian countries. H
 e is also a speaker at many international meetings\, an editor for technic
 al journal and book series in computer graphics and geometric modelling\, 
 and a recipient of an IBM Faculty Development Award and a National Science
  Foundation Presidential Young Investigator Award. Further information abo
