“…To align actions that are linear sequence of poses, which may vary in temporal execution, sequence alignment techniques such as Dynamic Time Warping (DTW) [18,23], Dynamic Manifold Warping (DMW) [14,15], and Canonical Time Warping (CTW) [29], have been employed to reduce the impact of temporal variations, [5,6,10,22]. These methods have however been criticized in situations where the temporal execution rate may provide some key information between two classes, e.g.…”
