Removes watersheds from the segmented image. The input image must be the entire original segmented image and assumes the outside border is filled with values < 0. To access this image call WatershedVincentSoille1991.getOutputBorder(). Each watershed is assigned the value of an arbitrary neighbor. 4-connect rule is used for neighbors. Doesn't matter if initial segmented was done using another connectivity rule. The value of each region i s reduced by one at the very end.
