I'm working on two-dimensional AR modelling and using the
from Matlab. In matlab there is a commend LPC which can compute the LP coefficients. How can I integrate to two dimension for image ?
The matlab code for one dimension signal is
[a]=lpc(signal,order)
est_signal = filter([0 -a(2:end)],1,signal);
error = signal-est_signal;
Using the same 1D code, do perform Column & row wise that will give 2D process output.
Hi
I advice you to see these documents. You will find what you need.
I hope that I helped you, let us know if you have another questions or you need more details.

There is an implementation at MATLAB Exchange provided by Simona Maggio 2D AR and 2D ARMA parameters estimation from the reference: "Two-dimensional ARMA modelling for breast cancer detection and classification" by N. Bouaynaya, J. Zielinski and D. Shonfeld in IEEE International Conference On Signal Processing And Communications, Bangalore, India, July 2010
