How do you define a "junction"?

[sreelekshmi ms]

sir , i am going to use this 8 connectivity for edge linking process. that is, for each end point of my image the 8 connectivity is checked till another end point is encountered. here i use the term junction for indicating that meeting point of two end points.

after checking for 8 connectivity and labeled it , i also need to find out the D4 distance b/w the points to obtain the link.

i think you may understand this.

please reply.

I think you should post a new question with example images to illustrate what you mean.
