We show that there exists a causal 2-D linear process in the non-symmetric half-plane having the same autocorrelations as a noncausal 2-D linear process in the whole-plane; this property is called the auto-correlation equivalence relation, and can be used for practical fitting and modeling of 2-D processes. Some causal 2-D AR models with various regions of(More)
