Video Colour Denoising Using Fuzzy and Directional Techniques
Francisco, Alberto Rosales, Jose M., Hima Jose · Sciyo eBooks · 2010
The proposed FD filter connects two commonly used in colour imaging techniques: directional processing where vector order statistics are employed, and fuzzy logic procedures that applied membership values found for pixels to be processed. FD filter has presented good performance in terms of noise suppression, edge and fine detail preservation, and chromaticity preservation properties, as well in visual subjective analysis. The proposed MML filter is able to remove impulsive noise and preserve the edges and details in gray scale and colour imaging. The proposed MML filter uses the robust MMestimator and utilizes an impulsive noise detector to provide better noise suppression, detail preservation, and in the case of colour imaging, provides better color retention. The VMML filter has demonstrated better quality of image processing, both in visual and analytical sense in comparison with different known colour image processing algorithms.
