Vertical Center-of-Mass Braking and Motor Performance during Gait Initiation in Young Healthy Adults, Elderly Healthy Adults, and Patients with Parkinson’s Disease: A Comparison of Force-Plate and Markerless Motion Capture Systems

Sensors
Background. This study tested the agreement between a markerless motion capture system and force-plate system (“gold standard”) to quantify stability control and motor performance during gait initiation. Methods.

3D Markerless Motion Capture: A Low Cost Approach

, 2016
A markerless motion capture technique is described for reconstructing three-dimensional biological motion. In the first stage of the process, an action is recorded with 2 CCD webcams. Then, the video is divided in frames. For each frame, the 2D coordinates of key locations (body joints) are extracted by the combination of manual identification (mouse ...

Markerless motion capture in sport: panacea or Pandora’s box?

Sports Biomechanics
This paper critically appraises the utility of markerless motion capture in the context of skill development and sports performance enhancement. If markerless motion capture is to be useful in a profiling or monitoring capacity, the amount of measurement error needs to be smaller than the amount of movement variability over iterative performance trials.

Comparison of Lower-Limb Joint Angles Obtained From Single-View Markerless and Marker-Based Three-Dimensional Motion Capture Systems Across Camera Locations

IEEE Access
This study compared lower-limb joint angles obtained from single-view markerless three-dimensional (3-D) motion capture (MoCap) systems with those obtained from a marker-based MoCap system across different camera locations. Three markerless MoCap systems,

The Poses for Equine Research Dataset (PFERD)

Scientific Data
Studies of quadruped animal motion help us to identify diseases, understand behavior and unravel the mechanics behind gaits in animals. The horse is likely the best-studied animal in this aspect, but data capture is challenging and time-consuming ...

Differentiable Biomechanics Unlocks Opportunities for Markerless Motion Capture

2025 International Conference On Rehabilitation Robotics (ICORR)
Recent developments have created differentiable physics simulators designed for machine learning pipelines that can be accelerated on a GPU. While these can simulate biomechanical models, these opportunities have not been exploited for biomechanics research or markerless motion capture.

Artificial intelligence and markerless motion capture in kinesiology

Kinesiology
Artificial intelligence and computer vision have made significant progress in recent decades, profoundly impacting many scientific and professional disciplines, kinesiology included. The development of markerless motion capture technologies has enabled precise tracking of kinematic and dynamic parameters of the human body movements without the need for
