Description: 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。分水岭的概念和形成可以通过模拟浸入过程来说明。在每一个局部极小值表面，刺穿一个小孔，然后把整个模型慢慢浸入水中，随着浸入的加深，每一个局部极小值的影响域慢慢向外扩展，在两个集水盆汇合处构筑大坝，即形成分水岭。
-Watershed segmentation method is a topology-based theory of mathematical morphology segmentation method, the basic idea is the image as a geodesic topology on the landscape, the image pixel gray value of each point indicates that the point of the altitude, Each local minimum value and its impact area known as the catchment basins, while the catchment basins of the border, however, the formation of a watershed. Watershed concepts and immersed in the process of the formation can be illustrated through simulation. A local minimum in each surface, piercing a small hole, and then slowly immersed in water the whole model, with the deepening of immersion, each local minimum value of the influence domain slowly expanded outward, in the two catchment the confluence of building the dam basin, namely, the formation of a watershed.

Description: we introduce the Color-based Catchment
Basin Merging Algorithm, an area-based segmentation approach
that is specifically designed to segment low-altitude
aerial images, as a preprocessing step to 3D reconstruction.
This approach extends the watershed-based Catchment
Basin Merging Algorithm, which is purely geometric,
by introducing color similarity as an additional criterion to
decide on the merging of evolving regions. Experiments performed
with real aerial images of varied nature demonstrate
that this modification eliminates over-segmentation problems
of the existing algorithm, allowing large-scale urban
scenes to be segmented in an accurate, reliable and fully automatic
way. Platform: |

Description: 分五个部分讲解：1.计算分割函数。图像中较暗的区域是要分割的对象。
2.计算前景标志。这些是每个对象内部连接的斑点像素。
3.计算背景标志。这些是不属于任何对象的像素。
4.修改分割函数，使其仅在前景和后景标记位置有极小值。
5.对修改后的分割函数做分水岭变换计算。-Divided into five sections explain: (1) Calculate the partition function. The dark areas in the image is the object you want to split.
(2) Calculate the prospect signs. These are spots connected pixels within each object.
(3) calculate the background logo. These pixels do not belong to any object.
(4) Modify the partition function, making only the minimum marker position in the foreground and a rear view.
5 watershed transform the modified partition function calculation. Platform: |
