Table 1 Explanation of detection methods
Method | Background calculation | Background update | Background update weights |
|---|---|---|---|
1 | Through sliding window | is performed during DWS is active | Fuzzy, given by Equation 5 |
2 | Through sliding window | is performed during DWS is active | Constant, w(r) = 1 in Equation 2 |
3 | Through sliding window | is not performed during DWS is active | Fuzzy, given by Equation 5 |
4 | Through sliding window | is not performed during DWS is active | Constant, w(r) = 1 in Equation 2 |
5 | Constant, from initial P A-scans at the start | is not performed at all | There is no update |
