79-86 specify in pertinent part the following limitations:
"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 performing an inverse
wavelet transform on said decoded low-frequency image and said
pair of high-frequency images, thereby obtaining said
digitized image." Accordingly, claims 1-6, 8-10, 12-14, 26-
33, and 79-86 require performing an inverse wavelet transform
on a pair of high-frequency images that were synthesized by
filtering a pair of edge images with an edge synthesis filter.
The examiner fails to show a suggestion of the
limitations in the prior art. He admits, "[n]either van der
Wal nor Schreiber explicitly provide for an inverse wavelet
transform on the low and high-frequency images ...."

at 5.) In terms of the AAPA, the appellant acknowledges "much
interest in the wavelet transform as a means of obtaining high
compression ratios with relatively modest amounts of
computation." (Spec. at 1.) Although the AAPA also discloses
