Self-filtering of noisy images via stochastic resonance

Self-filtering of noisy images via stochastic resonance

Nonlinear self-filtering and amplification of noisy, low-level images is demonstrated in a self-focusing photorefractive medium. Signal recovery depends sensitively on the parameters of the system and represents a new dynamical type of stochastic resonance.
