Hi all,

I have a problem when detecting arrow head. I find intersection point (red circle in image) but i have no idea for next step.

Some noise:

My new idea is find all direction from this point and check for abnormalities for each direction. (I don't know how to do it)

Thank everyone!

maybe you need to explain, what you're currently doing to find the intersection / show your code ?

i want to find/detect arrows (firstly, find arrow head). I used corner finding function (opencv as harris, MinEigenVal)) to find the intersection
