边缘检测和脊检测有什么区别？
What is the difference between edge and ridge detection?
标题已经足够说明，但引用 Wikipedia:
The purpose of ridge detection is usually to capture the major axis of
symmetry of an elongated object,[citation needed] whereas the purpose
of edge detection is usually to capture the boundary of the object.
However, some literature on edge detection erroneously[citation
needed] includes the notion of ridges into the concept of edges, which
confuses the situation.
但我仍然不清楚其中的区别。你能帮忙吗（最后举个例子）？
- Edges：高灰度值区域和低灰度值区域之间的边界。
- 脊：细线比它们的邻域更暗或更亮。
通常，如果我们在脊区域进行边缘检测，我们会得到一条双线，一条来自脊的每一侧。
这个答案是基于this answer，它给出了更详细的解释。
