Application No. 08/425,990
Relying on Ohsawa and Toriu for the aforementioned
reasons, the examiner fails to allege, let alone show, that
either reference cures the deficiency of Schreiber, van der
Wal, AAPA, and Carnahan. Because AAPA and Carnahan teach
performing an inverse wavelet transform only on data resulting
from a wavelet transform, we are not persuaded that teachings
from the prior art would have suggested the limitations of
"synthesizing a pair of high-frequency images by filtering
said horizontal edge image and said vertical edge image with
an edge synthesis filter ... and performing an inverse wavelet
transform on said decoded lowfrequency image and said pair of
high-frequency images"; "synthesizing a pair of high-frequency
images by filtering said horizontal edge image horizontally
with an edge synthesis filter, and filtering said vertical
edge image vertically with said edge synthesis filter; ...
performing an inverse wavelet transform on said high-frequency
images and said low-frequency image, thereby obtaining said
digitized image"; or "synthesizing a pair of high-frequency
images by filtering said pair of edge images with an edge
synthesis filter; and an inverse wavelet transform processor,
coupled to said up sampler and said edge synthesizer, for
