Patent

CA 2083158

The disclosure involves the use of a library of modulated wavelet- packets which are effective in providing both precise frequency localiza- tion and space localization. An aspect of the disclosure involves feature extraction by determination of the correlations of a library of waveforms with the signal being processed while maintaining orthogonality of the set of waveforms selected (i.e. a selected advantageous basis). In a dis- closed embodiment, a method is provided for encoding and decoding an input signal, comprising the following steps (80): applying combinations of dilations and translations of a wavelet to the input signal to obtain processed values (1610); computing the information costs of the pro- cessed values (1620); selecting, as encoded signals, an orthogonal group of processed values, the selection being dependent on the computed in- formation costs (1630); and decoding the encoded signals to obtain an output signal (1640). The wavelet preferably has a plurality of vanishing moments.
