Resampler changes #31

Closed nfaggian closed 12 years ago

nfaggian commented 12 years ago

Would like to add a bilinear resampler, perhaps also at some point some of the others listed here:

branched.

%timeit nearest.f(image.data, warp) 100 loops, best of 3: 2.79 ms per loop

%timeit cubic.f(image.data, warp) 10 loops, best of 3: 168 ms per loop

%timeit bilinear.f(image.data, warp) 100 loops, best of 3: 7.55 ms per loop

%timeit spline.f(image.data, warp) 10 loops, best of 3: 52.1 ms per loop

image.data.shape Out[18]: (512, 512)

Can someone please look at this code for me - seems to be a little bit off. Probably a small detail - the linreg example falls over very quickly.

I am missing MTF resampling in the list of resamplers.

$ time python linreg_pyramid.py > spline.log

real 0m24.468s user 0m23.620s sys 0m0.760s almost a x2 speedup! (i commented the plot.show() line out)
