Patent ID: 7120301

Claim:
A computer-implemented method for re-sampling discrete curves, wherein the discrete curves correspond to data, the method comprising: normalizing a plurality of discrete curves, wherein each discrete curve comprises a respective sequence of points; computing a weight function based on the plurality of discrete curves, wherein the weight function enhances differences between weighted discrete curves; determining a set of orthonormal polynomials based on the computed weight function, wherein the set of orthonormal polynomials comprises a set of basis functions; determining values for a plurality of zeros for one of the set of orthonormal polynomials, wherein the values for the plurality of zeros comprise re-sampling points for the plurality of discrete curves; and re-sampling each of the plurality of discrete curves based on the determined values of the plurality of zeros, thereby generating re-sampled discrete curves; wherein the re-sampled discrete curves are usable to analyze the data.
