From: Decoding hand movement velocity from electroencephalogram signals during a drawing task
Comparison on decoding performance of linear filter, Kalman filter and Kalman smoother. This figure shows the mean (bar) with SEM (error bar) of CC (the first row) and SNR (the second row) across the 5 subjects with different lag time using linear filter, Kalman filter and Kalman smoother. In the calculation of SNR, decoding error and measured hand velocity are considered as noise and signal respectively.
