A two-dimensional discrete stochastic model for representing images is developed. This representation has lower mean square error, compared to a standard autoregressive Markov representation. Application of the model to linear filtering of images degraded by white noise leads to scalar recursive filtering equations requiring only 0(N<sup>2</sup>log<inf>2</inf>N) computations for N x N images. The
Image processing, Kalman filtering, recursive filtering, two-dimensional filtering, image modelling.
