Color image denoising using loeal multiwavelet filtering

Abstract EN

This paper investigates the emerging notion of multiwavelets in the context of multirate filter banks, and applies a multiwavelet system to image denoising.

Multiwavelets are of interest because their constituent filters can be simultaneously symmetric and orthogonal and because one can obtain higher orders of approximation for a given filter length.

Local block filtering was a method for solving wavelet and multiwavelet transform.

In this paper we add this method for image denoising application and comparing it with another methods of thresholding.
