Segmentation > Watershed
Segments the Current Image by first interpreting its grayscale values as topography (ie, basins within level ground). A rainfall simulation is then run such that areas similar intensity are separated from others, where their brains fill to meet .
Choose to use markers to control watershed
2. Watershed Connectivity
- 8-pixel: Use 8-pixel connectivity to determine seeds for watershed
- 4-pixel: Use 4-pixel connectivity to determine seeds for watershed
3. Adjustment Connectivity
- 8-pixel: Use 8-pixel connectivity to adjust watershed strength by suppressing elevation minima before watersheding
- 4-pixel: Use 4-pixel connectivity to adjust watershed strength by suppressing elevation minima before watersheding
Thickness of watershed lines
Controls strength of watershed. Higher weaknesses result in few watershed lines.
