accurate and visually pleasing images is increasing. However, the images captured by …

At the crossing of the statistical and functional analysis, there exists a relentless quest for an
efficient image denoising algorithm. In terms of greyscale imaging, a plethora of denoising …

Image denoising has been a well studied problem in the field of image processing. Yet
researchers continue to focus attention on it to better the current state-of-the-art. Recently …

Image denoising algorithms often assume an additive white Gaussian noise (AWGN)
process that is independent of the actual RGB values. Such approaches are not fully …

Different methods for image denoising have complementary strengths and can be combined
to improve image denoising performance, as has been noted by several authors [11, 7] …

Over the past two decades, medical imaging and diagnostic techniques have gained
immense attraction due to the rapid development in computing, internet, data storage and …

The search for efficient image denoising methods still is a valid challenge, at the crossing of
functional analysis and statistics. In spite of the sophistication of the recently proposed …

Image denoising continues to be an active research topic. Although state-of-the-art
denoising methods are numerically impressive and approch theoretical limits, they suffer …
