Robust Sharpening Vector Median Filter

Abstract

In the paper a geneneralization of the Sharpening Vector Median Filter (SVMF) intended for the impulsive noise removal and edge sharpening in color images is presented. The novel enhancement technique utilizes a reachability measure between pixels, which combines the Euclidean distance and pixels similarities to the local neighborhoods. The performed experiments show that the new image enhancement framework offers much better denoising properties than the traditional Vector Median Filter and compares favorably with the SVMF.
