Table 1. Quantitative analysis of the displacement results obtained by using a peak-to-peak detection and cross-correlation method with and without bandpass filtering: root mean square error (RMSE) values were calculated after applying curve fitting on the estimated displacements by each method (BPF: bandpass filtering, C.C: cross-correlation, PTP: peak-to-peak).
