A correction: The light distribution with two LEDs would be problematic.

I could not reproduce your error. I am using latest official releases of numpy and cython on a linux box (do you use Mac?).  I am attaching the package I have on my PC, for the small chance it would help.

Hi all,

I just grabbed the latest bilateral filter from St?fan's repository,  
but I can't get it to work! I'm using a recent numpy SVN and the  
latest release of cython...

In [10]: bl = bilateral.bilateral(image, 2, 150)

NameError: np

I know very little about the internals of cython, so I can't figure  
this error out... it seems to be a problem with the 'cimport numpy as  
np' line in the pyx file, but beyond that I'm lost.

Let me know if I can provide any additional information,
