Cross sectional moments ? Here is a short calculation of 2-d moments of
order ij
;+
; NAME:
; i_moment
;
function i_moment,im,i,j
dim=double(im)
sdim=size(dim)
x=dindgen(sdim(1))
y=dindgen(sdim(2))
return,total(dim*(x^i#y^j))
end
;-
Maybe that ...

I don't know anything about this. I know how to fit
an ellipse to a blob. Maybe what you are looking for
are the axes of the ellipse.
