Get border pixels of labelled region

Hi all, Is there a way to get the pixels on the border of a labelled region in an image using skimage? I've done edge detection, and then filled the resulting shapes (after some edge linking), and would now like to be able to get the pixels on the border of each of these shapes. I would have thought that getting borders would be an option in regionprops, but it doesn't seem to be. Any ideas? Cheers, Robin
