[SciPy-user] fitting mixed gaussians

Hello,
i'm trying to perform mixed-gaussian fitting on some small greyscale
images (5x5 pixels, maximum 9x9). right now i'm using a leastsq
approach but it tends to get pretty slow and unreliable when it comes
to fit 4-5 2D gaussians even in such a small domain.
I've noticed PyEM and i have the feeling it might be useful for me,
but here i'm dealing with pixel intensities, not distributions. Any
hint is welcome!

Emanuele
