Review on Image Denoising Based on Contourlet Domain Using Adaptive Window Algorithm

This paper based on the characteristic of contour let transform for image denoising, paper presents adaptive window algorithm which uses directional information from the contour let transform and structure information of image for image denoising. In this method each sub band of the contour let is first fixed by autocorrelation function of contour let and then adaptive filtering is used to denoise the noisy image. Experiments will show that the proposed algorithm achieves better SNR value than current Contour let based image denoising algorithms.
