ABSTRACT:
In digital image processing, it is often necessary to alter the image by performing a zoom operation thereon. Such an operation is carried out with the use of a spatial interpolation unit. Described herein is a spatial interpolation unit which comprises a discrete set of filters for which at least some of the cut-off frequencies are logarithmically spaced.
