Hi!
I'm currently exploring Matlab right now. And I have a problem wich
is:

I have an image and I've found multiple centroids of the shapes that
are present, but I would like to limit the search for the centroids
(three for being more specific) that are within a certain angle.
I have an example above in which A, B and C are no more than 90º
apart, so that would be the centroids I would like to focus on.
Is there a function that does this for me?


*B
A*
*C


Thanks for your attention and Help

You haven't made it clear what angles you are talking about. An angle is defined by a vertex and two lines projecting from that vertex. Which are your vertices, which are your pairs of lines?
