<p>Compression of an initial dataset is implemented on a data processing system. The initial dataset can be transformed (210) into a group of initial wavelet coefficients using a wavelet basis function. Magnitudes of initial wavelet coefficients in the group of initial wavelet coefficients can be calculated (220). Initial wavelet coefficients having magnitudes beyond a cutoff value can be deleted (230). A compressed group of wavelet coefficients can be identified (240) from the wavelet coefficients remaining within the cutoff value. The initial dataset can be approximated (250) using the compressed group of wavelet coefficients and the wavelet basis function.</p> |
