Ok, I see now why the code is like that. Nothing really smart
comes to mind, apart from vectorizing the inner loop as in my
previous post. Of course, if the number of scattered points is
generally smaller than the number of rows/points in the image
then a loop over the points, adding their gaussian contribution to
the whole image, might be more efficient.

Cheers,
