10 March 1998 Identification of model parameters and correcting filters for space-variant distortions

We consider topics related to the construction of reconstructing filters for the correction of nonisoplanar distortions of defocusing type. The problem is tackled by the direct identification of shift-invariant models and reconstructing filters on small image fragments. We propose and study a new method for the selection of fragments based on analyzing the conjugation of vectors of independent variables with zero-space.
