Abstract :
Digital images are distorted by impulsive noise (IN) which caused by image sensors and communication channels in many practical applications. This noise may cause miscalculation of sharpness values in image fusion applications. In this paper, traditional criterion functions and frequency selective median filter (FSWM) based criterion function are evaluated for the fusion of multi-focus images in the presence of IN. Experimental results show that the FSWM filter is better than the other focus measures.
