In this paper, a robust watermarking technique is proposed using integer discrete cosine
transform, non-linear chaotic map and dynamic stochastic resonance (DSR). Firstly, the host …

In this paper, we first propose a brief overview of nonlinear resonance applications in the
context of image processing. Next, we introduce a threshold detector based on these …

Noise, traditionally defined as an unwanted signal or disturbance, has been shown to play
an important constructive role in many information processing systems and algorithms. This …

Two stochastic resonance (SR)-based techniques are introduced for enhancement of very
low-contrast images. In the proposed SR-based image enhancement technique-1, an …

The noise always plays a key role in different science and engineering applications. Here,
we study the effect of the addition of external noise (ie, stochastic resonance (SR) noise) in …

For almost 100 years, nonlinear science has attracted the attention of researchers to
circumvent the limitation of linear theories in the explanation of natural phenomenons …

A neural circuit exactly ruled by the FitzHugh-Nagumo equations is excited by a biharmonic
signal of frequencies f and F with respective amplitudes A and B. The magnitude spectrum of …

The fundamental quantum information processing task of estimating the phase of a qubit is
considered. Following quantum measurement, the estimation efficiency is evaluated by the …

We show that the structural similarity index is able to register stochastic resonance or
improvement by noise in nonlinear image transmission, and sometimes when not registered …

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 …
