New results in strip Kalman filtering

The strip Kalman filtering previously proposed by B.R. Suresh and B.A. Shenoi (ibid, vol.CAS-28, no.4, p.307-19, 1981) for image restoration is reconsidered. It is pointed out that the procedure given there for parameter estimation of the image model does not take into account the vector nature of the image process and as a result can lead to incorrect identification. It is also shown that for the composite dynamic model derived there the standard Kalman filtering equation cannot be applied, as the blur states in this model should be estimated one step ahead.<
