In this chapter we consider the conversion of the local time axis to a common time axis. This is the second step in the formation of a common representational format. To keep the discussion focused we shall concentrate on the methods based on dynamic time warping (DTW) including soft-DTW, drop-DTW and shape-DTW. We also consider the alignment of time series of different dimensionality (canonical time warping) and the alignment of multiple time series (dynamic barycenter average).
