Improvement of two-dimension AR model and application in simulation on surface profiles of steel plates
The order and parameter estimation is always difficult in two-dimension AR model because the two-dimension Yule-Walker equation does not have the property of uniqueness and identifiability as the one-dimension AR model. This paper provides an AR order estimation method for a two-dimension AR model,...

Summary: | The order and parameter estimation is always difficult in two-dimension AR model because the two-dimension Yule-Walker equation does not have the property of uniqueness and identifiability as the one-dimension AR model. This paper provides an AR order estimation method for a two-dimension AR model, and an AR model parameter estimation method on the basis of an autocorrelation function. A simulation example on surface profiles of some kinds of steel plates is given using this improved AR model with positive results. |
