It might be good to add some interpolation functions, but I'm not sure how realistic it is for 2 days' work (by me). There's some Netlib stuff that could probably "just" be wrapped, if you're interested, but it's ForTran and I don't know whether (doubt) you'd want to require that for compilation? Also, it might be too much along the lines of what I need and not what you want for the scikit, but it's just something to think about...
Fast interpolation algorithms using PyOpenCL may be worth looking at. I heard today of an interesting interpolation method that does not go exactly through data-points, but is extremely efficient to implement--will look into that some more. Either way, being able to size up and down large images efficiently would certainly be useful. Scipy's ndimage does B-spline interpolation well, although I've never been able to decipher exactly what happens below the hood :) Cheers Stéfan
