摘要: 利用独立分量分析的方法对脑电中眼电伪迹成分进行剔除。运用负熵最大算法将脑电信号分解成独立分量,利用伪迹脑地形图的特征,将伪迹分量分离,得到不含伪迹的脑电信号。实验结果表明,该算法具有较强的稳健性和实用性。

Abstract: The method is to use ICA remove ocular artifact from EEG.It is possible to extract signals that are statistically independent,and identify the spatial map associated to the artifactual component by Infomax algorithm.So the method can remove artifactual component,This work shows that ICA can be a very useful technique.Satisfactory results illustrate the performance and validity of the algorithm.
