Description: Watershed segmentation method, a segmentation method based on mathematical morphology and topology theory, its basic idea is that the image as a geodesic on the topological features, each pixel of the image gray value of the said at the altitude, every local minimum and the influence area is known as the water collecting basin, and the catchment boundary is the formation of watershed. The concept and formation of watersheds can be explained by simulated immersion processes. The surface of the value in every local minimum, pierce a hole, and then the whole model is slowly immersed in water, with the immersion deepening, the influence domain of each local minimum and slowly expand outward, to build a dam in the two water collecting basin confluence, which form a water ling.
