Abstract

Nonlinear extrapolation of the image spectrum is stated as a consequence of new mathematical results about definite positive extension or covariance extension. The main contribution of this method is its ability to incorporate a priori knowledge like positivity or some edges early detected in the image. The consequence is the gain in resolution when spatial or MRI images are considered.
