分水岭线是数学形态学中分割图像的基本工具。根据称为地形距离的距离函数给出了严格的定义。如果地形函数本身是一个距离函数，那么地形距离就与测地线距离函数相同，分水岭就与影响区域的骨架相同。然后对图论的经典最短路径算法进行了重新研究，从而得出新的分水岭算法，这些算法要么是新的，要么是更容易在硬件上实现的。
The watershed line is the basic tool for segmenting images in mathematical morphology. A rigorous definition is given in terms of a distance function called topographic distance. If the topographical function is itself a distance function, then the topographical distance becomes identical with the geodesic distance function and the watershed becomes identical with the skeleton by zone of influence. The classical shortest paths algorithms of the graph theory are then revisited in order to derive new watershed algorithms, which are either new or more easy to implement in hardware.
