image-processing - 边缘检测和脊检测有什么区别？

Question

标题已经足够了，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(最终用一些例子)？

Answer 1

边缘 :高灰度值和低灰度值区域之间的边界。

山脊 :比其邻域更暗或更亮的细线。

通常，如果我们对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。



此答案基于 this answer ，这给出了更详细的解释。
