AN ADAPTIVE LATTICE ALGORITHM FOR MODELING AND COMPRESSION OF PICTURE SIGNALS

This paper concerns the intraframe coding of pictures. Conventionally the predictive coding methods use a two dimensional linear predictor which is based on the autoregressive model of the picture. This paper proposes two versions of a twodimensional lattice algorithm for linear prediction. This algorithm is arrived at by representing the forward prediction error as a function of a lower order predictor. This method is computationally efficient and possesses all the advantages of the lattice algorithm
