So, there are a couple of ways you could do that. One is by using structuring elements as indicated in G & W. Another way would be to take a 3D method like described here in the surface approximation section (shameless plug):

and adapt it for 2D. 

There is nothing in scikits.image that will do this automatically, but it would be a useful feature so I'll add it to my TODO list.

I found the definition in "Gonzalez & Woods, p545", but I am not sure to implement the stuff.
