Edge detection and measuring lengths

Wes Armour
Hi All,

Is it possible to use ImageJ to automatically detect edges in an image
and then measure the distance between the two edges?

I have written an image J macro that is called from some c code, this
uses the process->find edges command and then writes the image to a text
image file. But this doesn't really make the code aware of where the
edges are, it just allows me to see them.

Thanks,

Wes.
