Re: generic non-linear filtering that support selem and boundary handling

Thanks for your reply, Stéfan. This is also what I was thinking. But I'm not sure whether it will still provide some performance gain by eliminating the outmost python for-loop through pixels. And if the filter is something as simple as np.std (or other well vectorized function), will it work OK? Will just calling back to python slow things down back? Thanks again!

LOL, I just saw all your testing, Stéfan, it is hilarious.

Hello, I added your channell to my log bot, you can now get logs here: http://sunpy.cadair.com/irc-logs/ (you have to select scikit-image from the dropdown at the top).

Two thumbs way, way up for trialing Gutter, looks nearly perfect for our purposes. Josh

Stuart, Stéfan, I think gitter looks fantastic! How about we go with that?

Yeah no problem, what channel do you want to use. I think I am already sitting in #scikit-image on freenode.

Hi, The other thing that the astropy repo does to manage the size of the gh-pages branch is make it an orphan branch on every build, so there is no history of the built notebooks only the empty ones.
