Image Denoising Using Hybrid Transforms
Engineering and Technology Journal,
2007, Volume 25, Issue 5, Pages 669-682
AbstractIn this paper a new family of transformation for image denoising is
presented, Multiridgelet and Walidlet transforms, which have been proposed
as alternatives to Discrete Wavelet and Multiwavelet transforms.
Walidlet transform is an intelligent tool for solving image processing
problems such as image denoising with straight edges, the general algorithm
of image denoising using discrete multiwavelet transform is introduced, then
followed by the general algorithm of image denoising 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.
