Beucher, Serge, and Fernand Meyer. "The morphological approach to segmentation: the watershed transformation." Optical Engineering-New York-Marcel Dekker Incorporated- 34 (1992): 433-433.
Input is a grayscale image with arbitrary number of dimensions, defining the heightmap, and labeling image defining where the seeds, i.e. the minima are. It needs to be defined whether a neighborhood with eight- or four-connectivity (respective to 2D) is used. A binary image can be set as mask which defines the area where computation shall be done. If desired, the watersheds are drawn and labeled as 0. Otherwise the watersheds will be labeled as one of their neighbors.
Output is a labeling of the different catchment basins.
