This paper proposes a detail-preserving image denoising method via cluster-wise progressive principal component analysis (PCA) thresholding based on the Marchenko …
We propose a novel principal component analysis (PCA)-based image denoising framework motivated by the fact that the PCA along with patch groups (PGs) can produce better …

At present, most denoising algorithms cannot determine whether a pixel is noise, but these use the same rules to process all pixels. Most denoising methods will filter out the original …

A novel image denoising algorithm using linear Bayesian maximum a posteriori (MAP) estimation based on sparse representation model is proposed. Starting from constructing …
This paper presents an efficient image denoising scheme by using principal component analysis (PCA) with local pixel grouping (LPG). For a better preservation of image local …
