Abstract
Cyclic Dynamic Time Warping (CDTW) is a good measure of contour shapes dissimilarity, but it is computationally expensive. We introduce a lower bound for CDTW inspired in the Bunke and Bühler that leads to a significant speed up of contours classification in real tasks, as the experiments show.
