Abstract

The problem of the determination of the spectral characteristics using the lifting scheme with the linear approximation of signals and the Haar wavelet-transform algorithm (à trous algorithme) is considered. These transforms are recommended for use in combination with standard methods. Based on analysis of the behavior of the wavelet coefficients, a method to localize the peaks and to determine the positions of maxima is proposed. The efficiency of the use of non-traditional wavelet transforms for the filtration and compression of spectral data and the localization of peaks, in particular, for neutron-scattering spectra, is demonstrated.
