图像骨架中的连接点(Junction point in image skeleton)

图像骨架中连接点的含义是什么？ 我正在使用opencv和c ++开发代码源来检测图像中的主要局部连接点。非常感谢advace。

What is the meaning of a junction point in image skeleton ? I am using opencv and c++ to develop a code source to detect the main local junction point in the image .Many thanks in advace .

连接点通常是两条线的交叉点。 看这个图像：

骨架（通常）指的是图像的骨架化。 这篇文章很有用：

所以我认为他们要求你做的是，让图像找到它的骨架然后找出哪个像素包含骨架线的交叉点。

opencv中的骨架化

A junction point is usually the intersection of two lines. See this image:

Skeleton refers (usually) to the skeletonization of an image. this article is useful:

So I think what they are asking you do is, to take the image find its skeleton then figure out which pixel contain the intersection of the lines of the skeleton.
