Abstract:-There is a considerable amount of literature about image denoising using fractal
image coding methods. Some new ideas where also reported using wave late domain. In this
paper we propose a mix wavelet-fractal denoising method. Using a non sub-sampled overcomplete wavelet transform. We present the image as a collection of translation invariant
copies in different frequency sub-bands. Within this multiple representation we do a fractal
coding which tries to approximate a noise free image. The inverse wavelet transform of the
fractal collage leads to the denoised image. Our results are comparable to some of the most
efficient known denoising methods.
