Re: Non-local means denoising
Hi Juan, yes, it's been a long time :-) (I took a new job in September and it's been pretty hectic since then!). My implementation is indeed 3-D. I'll start working on a PR this week-end then! For 3-D images the code is pretty slow due to the large size of the data, but I also have a pycuda + cuda implementation written by my PhD student William. You'll tell me if you're interested!

Hi,
it happens that I have an implementation of NL-means (implemented in C + cython). I have to clean it a little and then I can send it to the list. It would actually be interesting to convert it to pure Cython for further maintanability.

Ah, cool, congratulations on the new position then! I'm personally very interested, yes! Regarding scikit-image, I'm not sure whether Stéfan would be happy to go down the GPU route (and CUDA more specifically), but my feeling is that a very large chunk of scientific computing is going in that direction, so it would be good to have at least an optional dependency there...
