In the paper a novel filtering design intended for the removal of mixed impulsive and Gaussian noise contaminating color images is proposed. The new denoising scheme is based on the concept of the robustified vector median, which determines the center of a cluster of most similar pixels. The filter output is the average of pixels belonging to the cluster and thus it can be treated as an adaptive trimmed...
In this paper a new technique of mixed Gaussian and impulsive noise suppression in color images is proposed. The novel approach is based on a weighted average of pixels contained in the filtering block. The main novelty of the proposed solution lies in the new definition of similarity between a pixel and samples belonging to a small window centered at the central pixel of the processing block. Instead...
In this paper a novel, efficient extension of the vector median filter intended for the suppression of impulsive noise in color images is proposed. The new filter operates on the trimmed distances between color pixels belonging to the filtering window. The cumulated distances calculated for each pixel in the local window is used to perform the reduced vector ordering, which allows to find the pixel...
