In addition, claims 1-6, 8-10, and 12-14 specify in

filter ... and performing an inverse wavelet transform on said
decoded lowfrequency image and said pair of high-frequency
images." Similarly, claims 26-33 specify in pertinent part
the following limitations: "synthesizing a pair of high-

horizontally with an edge synthesis filter, and filtering said
