Image restoration using estimated parameters of image model and noise
statistics is presented. The image is modeled as the output of a 2-D n
oncausal autoregressive (NCAR) model. The parameter estimation process
is done by using the autocorrelation function and a biased term to a
conventional least-squares (LS) method for the noncausal modeling. It
is shown that the proposed method gives better results than the other
parameter estimation methods which ignore the presence of the noise in
the observation data. An appropriate image model selection process is
also presented. A genetic algorithm (GA) for solving a multiobjective
function with single constraint is discussed.
