The purpose of denoising is to remove the noisewhile retaining the edges and other detailed features as much aspossible. This paper, present a method for both image denoisingand sharpness enhancement. We approach the problems ofdenoising and sharpening by first adaptively segmenting theimage into clusters based on features that represent theunderlying local image structures (e.g., image details, edges,and textures). The key idea behind this approach is denoisingand sharpening according to the local image feature, so thatnoise amplification, undershoots, and overshoots can beeffectively avoided. The parameters which are used to test theperformance of the proposed method are i) Peak Signal to NoiseRatio (PSNR) and ii) Mean Absolute Error (MAE). Furtherthe results which are obtained using the proposed method interm of PSNR and MAE were compared with the earliestpublished works. The results clearly confirm the superiority ofour proposed method for sharpness enhancement and imagedenoising
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
