A Possible Model of Noise Enhanced Visual Perception in Human Vision

We demonstrate, through simulation, that a simple centre surround receptive field of vision is capable of exhibiting stochastic resonance. We also show that this could be used to model the nature of contrast sensitivity enhancement of human vision, through stochastic resonance, observed in psychophysical experiments.Comment: 5 pages, 6 figure

Can Centre Surround Model Explain the Enhancement of Visual Perception through Stochastic Resonance?

We demonstrate the ability of centre surround model for simulating the enhancement of contrast sensitivity through stochastic resonance observed in psychophysical experiments. We also show that this model could be used to simulate the contrast sensitivity function through stochastic resonance. The quality of the fit of measured contrast sensitivity function to the simulated data is very good.Comment: 4 pages,5 figure
