Perceptual Colour Image Sharpening using Fuzzy Morphological Agents

The processing of colour images to improve sharpness has nearly always been realized in RGB colour space. This paper extends our earlier algorithm for image sharpening based on fuzzy morphology to colour images. More specifically it explores the use of this algorithm in various colour domain. Part of the goal is to determine which colour space provides a result which does not differ immeasurably from the original with respect to chromaticity
