GMM estimation of 2D-RCA models with applications to texture image classification

A Boulemnadjel, F Hachouf… - IEEE Transactions on …, 2015 - ieeexplore.ieee.org
The 2D indexed random coefficients autoregressive (2D-RCA) models are obtained by
introducing appropriate random field coefficients to an AR model on Z 2. The study of such …
