Abstract An effective multi-focus image fusion algorithm based on random walk is proposed in this paper. Random and guided filter have attracted extensive attention fusion. usually used to solve probability problems it has a good smoothing effect, can preserve the gradient information of well. The combination two algorithms better retain edge input image. Six sets source images five existing me...
