Abstract:
Actual research on brain-computer interface system is analyzed.The basic structure and operational principle of this system are set forth.Methods of signal collection,feature extraction and selection classification of system signals are concluded.Latest analysis methods and existing defects of feature extraction and selection classification are introduced in detail.Problems existing in brain-computer interface system are also analyzed.Great advantages on feature extraction of wavelet transform & wavelet packet decomposition and wide prospects on selection classification of neural network are pointed out at last.
