I was researching bilateral filters and some variants for flattening areas of gray-scale images (eliminating features for sort of a pseudo-segmentation).

Bilateral filters work just OK, but of course they are miserably slow. There is a new generation of similar filters that promise extreme speed and better effectiveness. I was wondering if anyone has worked with Domain Transform, or Rolling Guided Filters, or if there are others.

There's a nice example of domain transform filters here: See the images of the statue about half-way down.

The code module is pretty large though, with support for SSE extensions and such.
