Adaptive Fractal and Wavelet Image Denoising
The need for image enhancement and restoration is encountered in many practical applications. For instance, distortion due to additive white Gaussian noise (AWGN) can be caused by poor quality image acquisition, images observed in a noisy environment or noise inherent in communication channels. In this thesis, image denoising is investigated. After reviewing standard image denoising methods as ...
متن کاملA Combination of Wavelet and Fractal Image Denoising Technique
In this paper, a new denoising technique for corrupted images with additive white Gaussian noise is presented. The technique used here is to combine the wavelet transform and the fractal transform with Recursive Gaussian diffusion. Digitalimage data compression apparatus includes a controller circuit for receiving digital image data and for processing the image data into blocks. The controller ...
متن کاملImage denoising using fractal and wavelet-based methods
There is a considerable amount of literature about image denoising using wavelet-based methods. Some new ideas where also reported using fractal methods. In this paper we propose a hybrid wavelet-fractal denoising method. Using a non-subsampled overcomplete wavelet transform we present the image as a collection of translation invariant copies in different frequency subbands. Within this multipl...
متن کاملFractal image denoising
Over the past decade, there has been significant interest in fractal coding for the purpose of image compression. However, applications of fractal-based coding to other aspects of image processing have received little attention. We propose a fractal-based method to enhance and restore a noisy image. If the noisy image is simply fractally coded, a significant amount of the noise is suppressed. H...
متن کاملWavelet Bayes Adaptive Image Denoising
The class of natural images that we encounter in our daily life is only a small subset of the set of all possible images. This subset is called an image manifold. The Adaptive Digital Image Processing applications are becoming increasingly important and they all start with a mathematical representation of the image. In Bayesian restoration methods, the image manifold is encoded in the form of p...
