数学形态学中的分水岭变换是一种强大而灵活的分割工具。然而，它不允许以其他方法的方式包括与区域边界特征有关的先验知识。本文介绍了局部约束分水岭变换，其中包括边界约束，通过修改底层路径定义的分水岭变换所依赖的。这种方法保持了分水岭变换的许多理想特性，例如定义良好的停止条件和有效的实现，同时在存在噪声或不完整边界的情况下提供更稳定的分割。
The watershed transform, from mathematical morphology, is a powerful and flexible tool for segmentation. However, it does not allow a priori knowledge relating to characteristics of region boundaries to be included in the way that other approaches do. This paper introduces the locally constrained watershed transform, which includes border constraints by modifying the underlying path definition upon which the watershed transform depends. This approach maintains many of the desirable properties of the watershed transform, such as well-defined stopping conditions and efficient implementation, while offering more stable segmentation in the presence of noisy or incomplete boundaries.
