Abstract: Existing watershed algorithm is sensitive to noise and has over-segmentation problem. Based on previous studies and combining with the current progress, this paper introduces watershed algorithm simulating flood and watershed algorithm simulating rain. It sums up four types of improved methods for watershed algorithm according to defects of the traditional algorithms. Problems and further research aspects of improved methods for watershed algorithm are discussed.

Key words: watershed algorithm, image segmentation, preprocessing filtering, labeling, region merging
