Özet

Impulsive noise (IN) produced by image sensors and/or communication channels corrupts images in many practical applications. This noise may cause miscalculation of sharpness values which, in turn, introduce considerable errors in fused images. In this paper, conventional focus measures and frequency selective weighted median filter (FSWM) based focus measure are evaluated for fusion of multi-focus images in the presence of IN. Experimental results are presented for several sets of images and the results show that FSWM based focus measure can provide better performance than other focus measures
