摘要: This paper made a research on the feature extraction and pattern recognition of left and right hands motor imagery EEG signals. In combination with the data from BCI Competition III, denoising preprocessing is carried out for EEG signals firstly; and then, the relative wavelet energy is extracted as a feature vector from the Channels C-3 and C-4 by use of the algorithm for relative wavelet energy, and pattern recognition is carried out by use of the radial basis function neural network .

In combination with the data from BCI Competition III, denoising preprocessing is carried out for EEG signals firstly; and then, the relative wavelet energy is extracted as a feature vector from the Channels C-3 and C-4 by use of the algorithm for relative wavelet energy, and pattern recognition is carried out by use of the radial basis function neural network . Simulation results show that the proposed method achieves good classification results.收起
