Claim 20:
21. The apparatus of claim 20, wherein the deconstructor comprises:
a downsampling phase deconstructor that performs a downward pass that operates on a plurality of levels of the pyramid data structure on a sequential resolution-by-resolution basis from higher to lower resolution using a downsampler to downsample at each level to generate a lower resolution downsampled instance at each level, wherein the highest level instance is the parametric database and the lowest level downsampled instance is also called the residue instance; and
an upsampling phase deconstructor that performs an upward pass in a sequential resolution-by-resolution basis from lower to higher resolution and starting at a next-to-lowest resolution level, and comprising an upsampler to upsample the next lower resolution downsampled instance at each level to generate an upsampled representation at each level, and comprising a difference generator to subtract the upsampled representation from the downsampled instance to generate a frequency isolation representation for that pyramid level.
