Segment nodes in an image

Hi,
I am new in image processing and I am trying to learn it by myself using Matlab.
I have a question based on an image I found and attached:
-How can I segment the left image that each node (I am not sure I use the correct terminology) will get different color and number (right image), is it also possible get other information like area in pixels?
Thanks a lot

You can skeletonize the image
bwSkel = bwmorph(binaryImage, 'skel', inf);
then find the branchpoints:
bp = bwmorph(bwSkel, 'branchpoints');
then remove them
binaryImage = bwSkel & ~bp;
then label
labeledImage = bwlabel(binaryImage);
That's just off the top of my head - I have not tested it.

OK, well, keep working at it because the algorithm should work but might need a tweak or two.

Basically, it takes an image in which we want to measure the angle between two straight objects, identifies these objects, then finds the intersection point and the angle between them. Maybe you can use these ideas to find the intersection points / nodes and detect the branches in your image.
