Study the effect of parameters used in stochastic resonance to enhance an image

Abstract

Enhancement is one of the challenging factors in image processing. The objective of enhancement is to improve the structural appearance of an image without any degradation in the input image. The enhancement techniques make the identification of key features easier by removing noise. One of the methods to enhance an image is the stochastic resonance (SR). In SR, noise is added randomly to the image to get back the information of the processed image which has been distorted. But the parameter choice of SR is too difficult to realize. In our paper we study the effect of those parameters over an image.
