Many non-linear systems perform better when some In this paper, the effect of SSR using Gamma noise has been reported, and the expression for cross-correlation has been derived. Furthermore, the same concept has been used in a watermarking application, where Gamma noise is added as the signature in the cover image. Gamma noise is later added externally to the watermarked image which maximizes the crosscorrelation at a particular value of the variance of the SR noise. The obtained results suggest that the maximum value of crosscorrelation Keyphrases: Gamma noise, cross-correlation, image processing, stochastic resonance, suprathreshold stochastic resonance, watermark
