The BLUR Project at Berkeley: Algorithms for Computer Generated Imagery, Computational Photography, and Aiding Human Vision

Speaker:  Brian A. Barsky – Berkeley, CA, United States
Topic(s):  Graphics and Computer-Aided Design

Abstract

The multidisciplinary BLUR project at UC Berkeley combines computer graphics with optics, optometry, and photography.  This research investigates 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, photo-realistic rendering algorithms for generating imagery with optically-correct depth of field, view camera simulation.  This talk will present an overview of rendering algorithms for simulating depth of field found in photographs and of vision-realistic rendering algorithms for simulating a subject's vision.  Our recent work on vision-correcting displays will also be discussed.  Given the measurements of the optical aberrations of a user’s eye, a vision correcting display will present a transformed image that when viewed by this individual will appear in sharp focus. This could impact computer monitors, laptops, tablets, and mobile phones. Vision correction could be provided in some cases where spectacles are ineffective.  One of the potential applications of possible interest is a heads-up display that would enable a driver or pilot to read the instruments and gauges with his or her lens still focused for the far distance.   This work was selected as one of 2014's ten "World Changing Ideas” by Scientific American.
