Figure 4

Example of four-connectivity watershed performed on an sample data. (a) shows the original gradient image values. (b) shows the direction of the steepest descending path for each pixel. Minima are highlighted with circles. (c) shows pixels where the steepest descending paths and minima have been labelled. The labels used for the direction of the steepest descending path are shown on the right side of the figure. (d) shows the data fully labelled. The pixels have been assigned to the label of their respective minima forming a catchment basin.
