分水岭分割方法，是一种基于拓扑理论的数学形态学的分割方法，其基本思想是把图像看作是测地学上的拓扑地貌，图像中每一点像素的灰度值表示该点的海拔高度，每一个局部极小值及其影响区域称为集水盆，而集水盆的边界则形成分水岭。-Watershed segmentation method, which is based on a topological theory of mathematical morphology segmentation method, the basic idea is that the image as a geodesic topology on the landscape, at each point in the image pixel gray value indicates that the point of the altitude, each local minimum value and its impact area known as the collection basin, while the water collecting basin boundary is the formation of Watershed
