Abstract: 本論文使用經驗模式拆解(Empirical Mode Decomposition,EMD)的方法去分析外傷性腦和脊髓損傷(Traumatic Brain and Spinal-cord Injury, TBSI)患者前額葉(Fp1、Fp2)的腦電波。正常受試者P300-BCI腦前額葉Fp1腦電波訊號(electroencephalogram, EEG)的本質模態函數能量占HHT參考總能量10%以上為IMF6, IMF7, IMF8, IMF9及IMF10。而TBSI患者P300-BCI腦前額葉Fp1腦電波訊號(electroencephalogram, EEG)的本質模態函數能量占HHT參考總能量10%以上為IMF3, IMF4, IMF7, IMF9, and IMF10。正常受試者P300-BCI腦前額葉Fp2腦電波訊號(electroencephalogram, EEG)的本質模態函數能量占HHT參考總能量10%以上為IMF7, IMF8, IMF9, and IMF10。而TBSI患者P300-BCI腦前額葉Fp2腦電波訊號(electroencephalogram, EEG)的本質模態函數能量占HHT參考總能量10%以上為IMF3, IMF4, and IMF9。正常受試者P300-BCI腦前額葉Fp1及Fp2腦電波訊號(electroencephalogram, EEG)的本質模態函數IMF10能量占 band各別為8.97%和3.54%。TBSI患者P300-BCI腦前額葉Fp1及Fp2腦電波訊號(electroencephalogram, EEG)的本質模態函數IMF9能量占delta band各別為10.71% 和10.08%。 根據上述的分析結果,在正常受試者和TBSI患者各自觀看6張不同的照片的實驗後,可以得知Fp1和Fp2 EEG的邊際化頻率訊號能量分佈特徵。
In the thesis, the empirical mode decomposition (EMD)method was used to analyze the P300-based brain–computer interface (BCI) with Fp1 and Fp2 electroencephalography (EEG) signals in subjects with Traumatic Brain and Spinal-cord Injury (TBSI). The ratios of the energy of P300-BCI Fp1 EEG signal of a normal observer to its refereed total energy for IMF6, IMF7, IMF8, IMF9, and IMF10 were larger than 10%, respectively. The ratios of the energy of P300-BCI Fp1 EEG signal of a TBSI observer to its refereed total energy for IMF3, IMF4, IMF7, IMF9, and IMF10 were larger than 10%, respectively. The ratios of the energy of P300-BCI Fp2 EEG signal of a normal observer to its refereed total energy for IMF7, IMF8, IMF9, and IMF10 were larger than 10%, respectively. The ratios of the energy of P300-BCI Fp2 EEG signal of a TBSI observer to its refereed total energy for IMF3, IMF4, and IMF9 were larger than 10%, respectively. The energy ratios of IMF10 of P300-BCI Fp1 and Fp2 EEG signals of a normal observer to their referred energy in the band were 8.97%, and 3.54%, respectively. The energy ratios of IMF9 of P300-BCI Fp1 and Fp2 EEG signals of a TBSI observer to their referred energy in the delta band were 10.71%, and 10.08%, respectively. From these analysis results, we see that the characteristics of the MFs for the Fp1, and Fp2 EEG signals of the normal and TBSI observers watching six different pictures, respectively.
