ABSTRACT:
A system that sharpens an image by scaling high frequency residual components of an image stored in decomposed base and residual format. The scaling of the residuals is performed as a high resolution image is being reconstructed from the base and residual images. The scaling is combined with residual decompression into a single table look-up operation.
