It extracts speech information concealed in audio and ten channels of imagined EEG (EEG-i) & vocalized EEG (EEG-v) signals. Three Wavelet Transform (WT) methods - Discrete Wavelet Transform (DWT), Wavelet Packet Decomposition (WPD) & hybrid of DWT & WPD (DWPD) with four-level decomposition is used to transform the signals into WT coefficients.

stationary signals like audio. This paper explores the use of the DWT in two applications. The first application is the automatic classification of non-speech audio data using statistical pattern recognition with feature vectors derived from the wavelet analysis. The second application is the extraction of beat attributes from music signals.

Face recognition is a system that can match human faces from images to video frames against those in a database. Wavelets are oscillations, having amplitudes beginning from zero, increases or decreases, then back to zero. Wavelet coefficients are used to extract features from hyperspectral data. These extracted features are called wavelet features.

The MLP used in the automatic instrument recognition task contains one hidden layer, with 8 neurons and an output layer with 3 neurons (see Fig. 3). Feature vectors for recognition are formed using 8 element vectors derived from the wavelet envelopes of audio signals columnwise. 8 8 3 + b{2} LW{2,1} + b{1} IW{1,1}
