Abstract
A system, method and computer program product are provided for compressing data. Initially, an interpolation formula is received. Such interpolation formula is utilized for compressing data. In use, it is determined whether at least one data value is required by the interpolation formula, where the required data value is unavailable. If such is the case, an extrapolation operation is performed to generate the required unavailable data value.
Claims21
A method for compressing data, comprising:
- receiving an interpolation formula;
- determining whether at least one data value is required by the interpolation formula, where the required data value is unavailable;
- and
- performing an extrapolation operation to generate the required unavailable data value;
- wherein the interpolation formula is utilized for compressing data.
A computer program product for compressing data, comprising:
- computer code for receiving an interpolation formula;
- computer code for determining whether at least one data value is required by the interpolation formula, where the required data value is unavailable;
- and
- computer code for performing an extrapolation operation to generate the required unavailable data value;
- wherein the interpolation formula is utilized for compressing data.
A system for compressing data, comprising:
- logic for:
- analyzing a wavelet scheme to determine local derivatives that a wavelet filter approximates;
- choosing a polynomial order to use for extrapolation based on characteristics of the wavelet filter and a numbers of available samples;
- deriving extrapolation formulas for each wavelet filter using the chosen polynomial order;
- and
- deriving specific edge wavelet cases utilizing the extrapolation formulas with the available samples in each case.
