Modern Edge-preserving filters: Domain-transform, Rolling Guided Filters

edit

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.
