Wavelet Time-frequency Analysis of Electro-encephalogram (EEG) Processing
Journal Title: International Journal of Advanced Computer Science & Applications - Year 2010, Vol 1, Issue 5
Abstract
This paper proposes time-frequency analysis of EEG spectrum and wavelet analysis in EEG de-noising. In this paper, the basic idea is to use the characteristics of multi-scale multi-resolution, using four different thresholds to wipe off interference and noise after decomposition of the EEG signals. By analyzing the results, understanding the effects of four different methods, it comes to a conclusion that the wavelet de-noising and soft threshold is a better conclusion
