Multiband Common Spatial Pattern based EEG Classification for Brain-Computer Interface
نویسندگان
چکیده
Thispaper presents a novel method for electroencephalography (EEG) based motor imagery classification for brain computer interface (BCI) implementation using the potential features extracted bandspecific common spatial pattern (CSP). The recorded EEG signal is bandpass-filtered into multiple subbands to capture the related rhythmic components of brain signals. The CSP features are then extracted from each of these bands. The linear discriminant analysis (LDA) based classifier is subsequently used to classify the relevant subband of EEG using the features extracted by CSP. Then the highest discrimination score among all the subbands is used as the norm for overall EEG classification. The experimental results show that the proposed method yields comparatively superiorclassification performance compared to prevailing methods.

AbstractAccuracy in identifying the subjects’ intentions for moving their different limbs from EEG signals is regarded as an important factor in the studies related to BCI. In fact, the complexity of motor-imagination and low amount of signal-to-noise ratio for EEG signal makes this identification as a difficult task. In order to overcome these complexities, many techniques such as variou...
