A robust Dynamic Time Warping algorithm for batch trajectory synchronization
Yang Zhang, Thomas F. Edgar · 2008
Derivative Dynamic Time Warping (DDTW) is useful in time series alignment to avoid singularity points and reduce the bias of alignment results towards the reference trajectory compare with Dynamic Time Warping (DTW). In order to apply DDTW to an industrial environment, a robust DDTW (RDDTW) algorithm is proposed by combining a moving window least squares procedure with DDTW. The developed algorithm is tested with noisy data and results are compared with those of DDTW and DTW.
