I just stumbled over the 3 lines of code on scikits' title page:

from skimage import data, io, filter

image = data.coins() # or any NumPy array!

edges = filter.sobel(image)

io.imshow(edges)

and wondered: Isn't it a bit funny to require an I/O module to show an image that is already loaded?

My apologies if that has been discussed before.
