Abstract

A concept was developed and a computer program was designed and implemented to model the eye, the brain, and the perception system. These models were used to study edge transformation through the human visual system. The eye model was developed using optical spread and neural sampling data along with different inhibition distributions. The effects of lateral inhibition on retinal edge response were studied and hypothetical brain transfer functions were calculated. The results of this study indicate that no single mechanism or linear model can explain both the sinewave response and edge perception for the human visual system. The eye and brain models were also used to predict edge perception. The applications and limitations of computer modeling are demonstrated for both human vision phenomena as well as artificial vision system development.
