User-Control of Matching

 

 

 

Global Orientation

 

This examples shows what type of matches are returned when global rotation is ignored.

Matching parameters: DTW, rotational parameterization, full-body area, no global position, no global rotation.

 

No Global Rotation

  1. The query
  2. The  best n-matches, from best to worst.

 

 

 

Avoiding Trivial Matches

 

Trivial matches are avoided by enforcing a minimum distance between valid matches.

Matching parameters: DTW, rotational parameterization, full-body area, no global position, no global rotation.

 

No minimum distance enforcement

All matches are slightly shifted version of best match.

With minimum distance enforcement

 Matches are at least 0.8 of length original query apart.

Keyframe Query

 

The query does not have to be an existing mocap sequence. It can instead be defined manually as a series of keyframes by the animator.

Matching parameters: LCSS, rotational parameterization, full-body area, no global position, no global rotation.

  1. The query keyframes with the base pose in between.
  2. The query keyframes frozen until next keyframe.
  3. The query keyframes interpolated using spherical cubic interpolation.
  4. The best n-matches to the above interpolated query, from best to worst.

 

 

 

Query Mirroring

 

A single mirrored query finds symmetric matches.

Matching parameters: LCSS, rotational parameterization, full-body area, no global position, no global rotation.

 

No query mirroring

 

With query mirroring

 A better top match is found, which could not have been found without mirroring.
