小波变换在视觉诱发脑电信号提取中的应用——提取视觉诱发脑电信号的新方法之三

摘要

Procedure for extracting the VEP （Visual Evoked Potential） signal via the well-known Mallat algorithm in the realm of wavelet analysis is derives in this paper. Based on extensive simulations onthe VEP extraction, a real clinical application has been performed. Numerical simulation and clinical application results have shown that the wavelet transform technique can accurately identify the latency of the VEP by using a significantly reduced number of visual stimulation.%利用数据序列分解与重构的Mallat快速算法导出了可用于视觉诱发脑电（VEP）信号提取的小波去噪算法，并在大量提取VEP的仿真研究的基础上进行了临床实际应用实验． 数字仿真和临床应用结果均表明，用小波变换方法可以在大幅减少视觉刺激次数的前提下识别VEP的潜伏期P100．
