Abstract
Color fringe is an artifact that should be removed in a color digital image. This paper proposes a detection method of color fringe in narrow color regions. Near-saturation region (NSR) information as well as gradient magnitudes and directions of RGB color components are used to detect transition regions, in which color fringe occurs. Four gradient directions are used in order to improve the performance of color fringe detection. NSR is used to prevent excessive detection of possible color fringe regions. Then, the detected color fringe is removed using the color difference values. Experimental results show the effectiveness of the proposed color fringe removal method.
