Perception enhancement of subthreshold noisy image with vibrational resonance

Abstract

The authors reveal the first evidence of subthreshold noisy image perception, which takes benefit of the vibrational resonance phenomenon. Indeed, an appropriate amount of a high-frequency perturbation allows revealing a grey level noisy image through a threshold detector.
