2d To 3d Video Motion Capture With Multi Person Skeletal Tracking

via “pose landmark detection for body keypoint tracking”

Google's cross-platform on-device ML framework with pre-built solutions.

Unique: Provides 33-point full-body skeleton with 3D coordinate estimation (including depth via monocular estimation) and per-landmark visibility scores, optimized for on-device inference on mobile and web platforms; uses a single-stage neural network approach rather than multi-stage pipelines.

vs others: Faster and more mobile-friendly than OpenPose or MediaPipe's legacy Pose solution, includes 3D coordinate estimation without requiring depth cameras unlike some alternatives, but limited to single-person pose and requires full-body visibility unlike multi-person pose systems.
