I am new user of ImageMagick.. How is it possible to find all the circles in a drawing?
for example, I am interested to get the X,Y location of all circles in an architecture drawing (white & black) that contains circles along with other shapes and numbers.


Thank you

I don't know that IM can do that. But there is a technique see :

Thank you for your reply

I also stumbled on this: ITK <www.itk.org>

I am reading its documentation and it seems to be very good at image segmentation (in medical field)..

Do you know any thing about it?

No, sorry, I have never heard of it, but it looks interesting.
