Image denoising using hybrid transforms

Abstract EN

In this paper a new family of transformation for image demising is presented, Multi ridgelet and Walidlet transforms, which have been proposed as alternatives to Discrete Wavelet and Multi wavelet transforms.

Walidlet transform is an intelligent tool for solving image processing problems such as image demising with straight edges, the general algorithm of image demising using discrete multi wavelet transform is introduced, and then followed by the general algorithm of image demising using Walidlet transform that is proposed here in order to achieve better results than that for Walidlet thresholding, finally, a comparative study is presented to show the differences between a mentioned algorithms.
