IDL QUESTION

[Brian Koss <bakoss(at)rainbow.uchicago.edu>]

???

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...
