Claim 21:
22. The apparatus of claim 20, wherein the reconstructor comprises:
an upsampling phase reconstructor that performs an upward pass that operates on a plurality of levels of the pyramid data structure on a sequential resolution-by-resolution basis from lower to higher resolution and starting at the next-to-lowest resolution level, to produce a frequency blended representation at each resolution level using:
an aggregate contrast factor processor that processes the frequency isolated representation at that pyramid level to generate a modified frequency isolated representation;
an aggregate headroom factor processor that performs at least one of: upsampling the frequency blended representation for the next lower resolution pyramid level and modifying the result; to generate a modified blending representation; and

a frequency blender with dynamic headroom management and throttling that blends the modified frequency isolated representation at that pyramid level with the modified blending representation to generate a frequency blended representation at that pyramid level, and returns one or more of the frequency blended representations as the enhanced parametric database.
