markerless

Markerless describes motion capture or tracking technology that works without requiring physical markers, sensors, or special suits attached to the subject.

Traditional motion capture systems use reflective dots or sensors placed on a performer's body, but markerless systems use cameras and software to track movement directly from video.

The studio switched to markerless motion capture to speed up production.

This approach is increasingly common in animation, video games, sports analysis, and medical rehabilitation.
