OVERVIEW

Visual Sciences Program

The area of interest of this R&D program is human vision.

Our approach to the human visual system is predominantly bottom-up.

Our methods encompass psychophysical experiments, mathematical modeling, computer simulations, and systems engineering.

Our general goals are:

Our current research interests are the spatial, temporal and chromatic interactions that take place in early vision processes, from retina to visual cortex. We are in search of the links between objective (physical) representations of chromatic and achromatic variables in the visual stimulus, and the corresponding subjective (perceptual) representations.

In addition to studying problems on vision, in the last 5 years we have emphasized applied research, like measuring image degradation in satellite imagery, processing of digital color images of still and dynamic scenes (digital video), as well as analyzing CCD capture and decoding of digital color imagery with the aim of developing novel systems and techniques.

Two of the technologies developed by this Program are under active upgrading and commercialization; they are 1) the SRI Eyetracker, a double Purkinje-image optoelectronic instrument, and 2) Chromaplex*, a computational technology for processing and compression of digital color images.
