Abstract
A new method to obtain the 2D ML spectrum estimation using recently de veloped orthogonal 2D lattice filters for AR modelling is reported. It is shown that the reciprocal of thr 2D ML estimate is equal to the av erage of the reciprocals of the AR spectra obtained from the unended o rthogonal forward or backward prediction error filters in the 2D AR la ttice structure.
