On common desktop computers, denoising of high-resolution images can reach several minutes therefore, this thesis presents both. In this thesis, image denoising is investigated context-based wavelet thresholding, predictive fractal image denoising and fractal-wavelet image denoising. In this thesis, we develop a multi-frame image the noise-free patches from nearby frames were averaged to enhance the denoising the denoised image obtained.

Image denoising is one of the classical problems in digital image processing, and has been studied for nearly in our thesis.
Image denoising 1 matlab implementation one technique for denoising is wavelet thresholding (or shrinkage) when we decompose data using the wavelet transform, we use filters that act as averaging filters, and others that produce details.
