Sinc-Windowing and Multiple Correlation Coefficients Improve SSVEP Recognition Based on Canonical Correlation Analysis

Grand average across subjects and runs of the classification accuracies (a) and ITR (b) for all the considered methods. The black-dashed line indicates the upper confidence interval of the chance level (a) and its corresponding ITR (b). Note that chance level is slightly different for the different time windows, as the consideration of a larger time window implies a reduction in the number of trials per class.
