Table 2 The statistical analysis results of ΔSNR (in dBs) for slow, medium and fast head movements.
From: Motion artifact cancellation in NIR spectroscopy using discrete Kalman filtering
Head Movement Speed | Statistical analysis for ΔSNR (Kalman vs adaptive filter) | Statistical analysis for ΔSNR (Kalman vs Wiener filter) |
|---|---|---|
Slow | S. (t = 2.760, p < 0.020) | N.S. (t = -1.953, p < 0.079) |
Medium | S. (t = 2.783, p < 0.019) | N.S. (t = -0.385, p < 0.708) |
Fast | S. (t = 3.820, p < 0.003) | N.S. (t = -1.274, p < 0.231) |
