Adaptive Manifolds for Real-Time High-Dimensional Filtering
If you haven't seen this SIGGRAPH paper yet, you will probably find it very interesting. Has potential to both speed up and improve several of your filters when processing the filter stack. (or just provide means for creating completely new filters) Includes some example code.

it includes matlab code, which is not useful. plus, using 15 manifolds is exactly the same storage as the bilateral grid for 3d in practise, so i'm not immediately convinced it will improve things for us. also their non-local means results seem to employ pca for reduction of dimensionality and seem to be less optimal than specialized implementations.
that being said i'd like to see a real comparison and found the paper very interesting and exciting to read. so if anyone implements it, let me know how it goes (i won't code it).
