The aim of the present paper is to give an efficient scheme for denoising and edge detection of images. The main idea is based on rationalized Haar functions. Up to now, these functions were being used in solving integral equations and differential equations. But in this paper, we have used rationalized Haar functions for denoising and edge detection of the standard images. Experimental results show the accuracy of using rationalized Haar functions in edge detection and denoising.
