摘要
本文导出了二维离散随机模式自相关模型的z变换,建立了z变换系数的线性模型并进行模型的辨识。对二维可分指数模型提出对数辨识法。对地形模式和图象模式辨识的结果,证实了方法的正确性和结果的精确性。
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.
