Figure 1

General preprocessing and postprocessing steps involved when using the watershed. Also it shows the two main steps involved in the watershed transform. Firstly find the direction of steepest descending path and label the pixels to point in that direction. Using the direction labels, the pixels will be relabelled to match the label of their corresponding catchment basin.
