Abstract
An image interpolator for converting an original image into an enhanced image, the interpolator including rule logic for embodying a rule specifying how pixel patterns associated with first subband image data transform into corresponding pixel patterns associated with second subband image data, the first and second subband image data being derived from a reference image; and conversion logic for generating the enhanced image from the original image based upon the rule.
