Aj. Willis et al., LOCALIZED PRIOR KNOWLEDGE AND OPTIMAL INTERPOLATION IN HIGH-RESOLUTION TOMOGRAPHY, IEEE transactions on biomedical engineering, 45(4), 1998, pp. 538-541
The problem of electromagnetic tomographic reconstruction is approache
d in terms of the derivation of a minimum norm interpolator, incorpora
ting a priori knowledge gained from a previous reconstruction. An algo
rithm is suggested for the initial estimate and both images are compar
ed to that of bilinear interpolation.
