Mixed Signature: An Invariant Descriptor for 3D Motion Trajectory Perception and Recognition

Figure 12

Matching two similar trajectories (whose distance should be 0) using DTW, CDTW, and our method. The distance of (c) is much more accurate with cubic polynomials interpolation. The curves of dashed line in (b) and (c) are the original trajectory.
