A non-stationary adaptive model for recursive image filtering.

ABSTRACT
A new approach to non-homogeneous image modelling for recursive filtering problems is developed. The main assumption is that the whole non-homogeneous image can be modelled by a collection of homogeneous open subregions where the 2-D signal is regular enough to be well described by a smooth two-dimensional gausssian process. The boundary points between two adjacent homogeneous subregions are the image edges which represent sharp discontinuities (inhomogeneities) in the signal distribution. A non-stationary state-space representation with structural information on the image non-homogeneity is obtained. This allows the model tovary in an adaptive manner according to the presence of spatial discontinuities. Finally, the reported simulation results show high filter performances.
