Reliable and Efficient Approach of BOLD Signal with Dual Kalman Filtering

Table 2

The fact that joint filtering requires half of the iterations that are required by dual filtering has been taken into account.

Algorithm Dimension of state vector Total flops

Joint UKF 𝐿 = 𝐿 𝑥 + 𝐿 𝑤 = 9 285
Dual UKF 𝐿 𝑥 = 4 , 𝐿 𝑤 = 5 170
