Analysis of Image Restoration Techniques using Fourier and Wavelet Transform
Abstract
The task of image restoration is to restore the image removing all of the degradations present in it. This degradation may be due to the motion or due to presence of noise. This noise can be of any type such as Gaussian, salt and pepper, speckle or poisson. We have mainly considered salt and pepper noise. In this paper, standardized techniques have been used for image restoration which involves techniques using fourier transform and wavelet transform. Also, quantitative evaluation of various image restoration methods has been done based on parameters such as contrast, correlation, energy and homogeneity.
