Abstract :
A new wavelet thresholding function which has continuous derivative was discussed in this research. The wavelet thresholding denoising method and TOC (third-order correlations)-based filtering approach were used in extracting visual evoked potential (VEP). The experimental results showed that the new thresholding function combined with TOC-based filters have good performance in analyzing visual evoked potential (VEP)
