Classification on Be stars using feature extraction based on discrete wavelet transform
Bromová, P. ; Bařina, D. ; Škoda, Petr ; Vážný, Jaroslav ; Zendulka, J.
We describe the initial experiments in the field of automated classification of spectal line profiles of emission line stars.
Feature extraction using wavelet power spectrum for stellar spectra clustering
Škoda, Petr ; Bromová, P. ; Zendulka, J.
This paper analyses the capabilities of using wavelet power spectrum for clustering of Be-type stars spectra. We propose a method using discrete wavelet transform for feature extraction and the wavelet power spectrum as a feature vector.
