Effect of DTW temporal window - 1 |
The following example shows the effect of the DTW window size on the match results. The matching window size is increased from 1 to 40 keyframes. That means the dynamic warping algorithm will look for the closest point that is temporally +δ or -δ keyframes (in the match) away from the current keyframe (in the query), where δ is the window size. If δ=1, this is equivalent to Euclidean matching. We show the returned matches for each window size.
The query is a short sitting motion 53 keyframes long (or 2.2 seconds).
Matching parameters: DTW, rotational parameterization, full-body area, no global position, no global rotation.

Effect of DTW temporal window - 2 |
Same as above except that the query motion is a slow walking motion 56 keyframes long (or 2.3 seconds).
Matching parameters: DTW, rotational parameterization, full-body area, no global position, no global rotation.
