Localized prior knowledge and optimal interpolation in high-resolution tomography.
The problem of electromagnetic tomographic reconstruction is approached in terms of the derivation of a minimum norm interpolator, incorporating a priori knowledge gained from a previous reconstruction. An algorithm is suggested for the initial estimate and both images are compared to that of bilinear interpolation.
