Abstract :
The authors use wavelet multiresolution decomposition to track the latency of the visual evoked potentials. They also make use of the correlation coefficient to revise the shift of the latency. In searching the peak location, the authors use an automated step, which is based an the preceding peak, for more detailed searching
