I have images of polygons connected edge to edge in a quasiperiodic array, like the one I
have attached to this message...
The images are black and white and the edges of the polygons are distinguisable because
they are straight lines.
I would love to be able to use IDL to find the vertices in this image.
Essentially this will give me all the corners in the image.  Is there a
function in IDL that does such a thing (find intersections or verticies)?
Thanks for your time...
