In determining the point spread function (PSF) of digital images, the
estimation of the parameters of an ARMA model is usually reduced from a 2-D
problem into a 1-D problem.
Does anyone know of the necessary conditions for this to be possible? A
reference could be very useful.
I would also appreciate some comments about the fitting of spatial models to
digital images corrupted with noise.
Thanks
