Abstract :
Spectral estimation for multiple 2-D signals by autoregressive modeling is discussed. The procedure computes the entire spectral matrix of autospectra and cross spectra for the set of 2-D signals. Specific differences between AR models for this problem and those for lower dimensional problems are discussed. Experimental results are presented
