Claim:
1. An image sharpening method comprising: capturing an image; decomposing, by an image system, the image into a plurality of image-representation components; transforming, by the image system, each image-representation component of the plurality of image-representation components to obtain an unsharpened multi-resolution representation for each image-representation component, wherein a multi-resolution representation comprises a plurality of transformation level representations; transporting, by the image system, sharpness information from an unsharpened transformation level representation of a first one of the plurality of image-representation components to a same transformation level representation of an unsharpened multi-resolution representation of a second one of the plurality of image-representation components to create a sharpened multi-resolution representation of the second one of the image-representation components, wherein the transported sharpness information modifies sharpness information in the same transformation level representation of the unsharpened multi-resolution representation of the second one of the plurality of image-representation components; transforming, by the image system, the sharpened multi-resolution representation of the second one of the plurality of image-representation components to obtain a sharpened image; and displaying the sharpened image on a display device.
