Wavelet Based Feature Extraction for Clustering of Be Stars
Be star, feature extraction, wavelet transform, wavelet power spectrum
The goal of our work is to create a feature extraction method for classification
of Be stars. Be stars are characterized by prominent emission lines in their
spectrum. We focus on the automated classification of Be stars based on typical
shapes of their emission lines. We aim to design a reduced, specific set of
features characterizing and discriminating the shapes of Be lines. In this paper,
we present a feature extraction method based on the wavelet transform and its
power spectrum. Both the discrete and continuous wavelet transform are used.
Different feature vectors are created and compared on clustering of Be stars
spectra from the archive of the Astronomical Institute of the Academy of Sciences
of the Czech Republic. The clustering is performed using the k- means algorithm.
The results of our method are promising and encouraging to more detailed
analysis.
