gaussian bivariate fit

Christophe KLOPP
Hi,

I'm searching a macro or plugin to test if a ROI is fitting a bivariate
gaussian distribution?

Thanks'

Christophe

If it is a 2D gaussian and you knew the mean and SD of the 2D gaussian (I am
assuming it is symmetrical), you could run a correlation analysis of the
image and a sample gaussian you create as another image.
For example one could do that with this plugin, I think.

Would that do?

Cheers,
