Abstract:
1. A computerized method comprising: applying a multi-level transform to generate descriptions containing compressed data representing source data and further comprising predictor data from each level of the multi-level transform, wherein each level of the multi-level transform comprises a description generation operation and variable support filters for compaction, wherein one level of the transform generates descriptions from input data and compacts the input data by filtering within the generated descriptions and wherein the one level skips over a first number of description boundaries when compacting the input data, and wherein a subsequent level skips over a second number of description boundaries, and wherein the first number is different from the second number; and generating, by a computer, a secondary description corresponding to a primary description, the primary description comprising data output from a final level of the transform and the secondary description comprising an error signal associated with the primary description.
