  Abstract: Dynamic Time Warping (DTW) is a well-known similarity measure for time series. The standard dynamic programming approach to compute the dtw-distance of two length-$n$ time series, however, requires $O(n^2)$ time, which is often too slow in applications. Therefore, many heuristics have been proposed to speed up the dtw computation. These are often based on approximating or bounding the true dtw-distance or considering special inputs (e.g. binary or piecewise constant time series). In this paper, we present a fast and exact algorithm to compute the dtw-distance of two run-length encoded time series. This might be used for fast and accurate indexing and classification of time series in combination with preprocessing techniques such as piecewise aggregate approximation (PAA).
