Fig 10. Application of the Okada filter with different window lengths to fMCI data.

The original fMCI trace (top) was filtered by the Okada filters with window lengths of three, five and seven frames (left). The same fMCI data as Fig 3 were filtered. The S/Ns in the filtered traces were compared to the original S/Ns (middle), and the effect of the Okada filter with the windows of five and seven frames was compared to that with three frames (right).
