Abstract

In this paper the z transform of the autocorrelation model for two-dimensional discrete random pattern is derived

and the linear model for the coefficient of z transform is established and identified. The logarithm identification approach to a two-dimensional separable exponential model is presented. The validity of the methods and the precision of the results are verified by the identification results for several terrain and image patterns.
