Efficient algorithm for superresolution in image processing

New mathematical results about extrapolation of an image spectrum yield an efficient algorithm for superresolution in image processing. A significant power resolution is gained with the help of a new nonlinear interpolation method. The principle of this new method is described and illustrated by the treatment of (small) real images.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
