Abstract

Meyer watershed algorithm, which creates watershed lines to the output image, and its extended split-and-merge version are further analyzed in this paper based on our previous work. Specifically, it is shown that no permanently isolated areas exist in the output of the Meyer watershed algorithm when applied to an eight-connected square grid. The scanning order dependency of watershed algorithms is also studied. First, the different scanning order operations which are implementation dependent are identified; then their effects on the output are analyzed. Finally, an alternative implementation of the split-and-merge watershed algorithm is presented which detects isolated areas using a new technique; the goal is to illustrate and analyze the operations of the split-and-merge watershed algorithm.
