ABSTRACT:
The resolution of an original image, represented as a pixel array, is increased by applying a spectral transformation to the pixel array, producing a spectral array representing the image, and then applying an inverting spectral transformation to produce a larger pixel array. The inverting spectral transformation is of a kind designed to convert high frequency spectral components not present in the original image or identified by the spectral array. These high-frequency terms of the inverting spectral transformation are either ignored or supplied with zero values. As a result, the final, larger pixel array has the same spectral distribution as the original pixel array, but a larger number of pixels.
