Abstract

Professor Brian A. Barsky from UC Berkeley will present an overview of his research combining computer graphics with optics, optometry, and photography. This research has investigated mathematical models to describe the shape of the cornea and algorithms for cornea measurement, scientific and medical visualization for the display of cornea shape, mathematics and algorithms for the design and fabrication of contact lenses, simulation of vision using actual patient data measured by wavefront aberrometry, rendering algorithms for realistic depth of field, view camera simulation, and custom vision correction by computing an altered display that when viewed by the patient would appear in sharp focus for this particular individual.

Speaker Biography

Brian A. Barsky (http://www.cs.berkeley.edu/~barsky/biog.html) is Professor of Computer Science (http://http.cs.berkeley.edu/) and Vision Science (http://vision.berkeley.edu/VSP/), and Affiliate Professor of Optometry (http://spectacle.berkeley.edu/), at the University of California (http://www.reg.uci.edu/SANET/uc.html) at Berkeley (http://www.berkeley.edu/). He is a member of the Joint Graduate Group in Bioengineering (http://bioeng.berkeley.edu/gradhome.php), an interdisciplinary and inter-campus program, between UC Berkeley (http://www.berkeley.edu/) and UC San Francisco. (http://www.ucsf.edu/) He has been a Visiting Professor and Researcher at Universities around the world. He received a D.C.S. in engineering and a B.Sc. in mathematics and computer science at McGill University (http://www.mcgill.ca/) in Montréal (http://www.muc.qc.ca/cum-an/visiteur/indxvisa.htm). He studied (http://http.cs.berkeley.edu/%7Ebarsky/Jpg/cornell.html) computer graphics and computer science at Cornell University (http://www.cornell.edu/) in Ithaca (http://www.ci.ithaca.ny.us/), where he earned an M.S. degree. His Ph.D. degree is in computer science from the University of Utah (http://www.utah.edu/) in Salt Lake City (http://www.ci.slc.ut.us/). He is a Fellow (http://www.cs.berkeley.edu/%7Eddgarcia/forbrian/BrianAcademyOfOptometry.jpg) of the American Academy of Optometry (http://www.aaopt.org/) (F.A.A.O.).

He is a co-author and co-editor of books on computer graphics. He has published 120 technical articles in this field and has been a speaker at many international meetings. He was the editor of several series on Computer Graphics. He was the Technical Program Committee Chair for the ACM SIGGRAPH (http://www.siggraph.org/) '85 conference.

He has been working in spline curve/surface representation and their applications in computer graphics and geometric modeling for many years. He is applying his knowledge of curve/surface representations as well as his computer graphics experience to improving videokeratography and corneal topographic mapping, forming a mathematical model of the cornea, and providing computer visualization of patients' corneas to clinicians. This has applications in the design and fabrication of contact lenses, and in laser vision correction surgery. His research, called Vision-Realistic Rendering is developing new three-dimensional rendering techniques for the computer generation of synthetic images that will simulate the vision of specific individuals based on their actual patient data using measurements from a instrument a Shack-Hartmann wavefront aberrometery device. This research forms the OPTICAL (http://http.cs.berkeley.edu/optical/) (OPtics and Topography Involving Cornea and Lens) project. The Berkeley BLUR Project (http://www.cs.berkeley.edu/%7Ebarsky/Blur/) is developing techniques for depth of field for both synthetic images and photographs.
