Visual effects studio Digital Domain is introducing a new version of its Masquerade facial motion capture system, which eliminates the need for actors to wear tracking markers on their faces ...
Markerless face tracking has progressed to commercial systems such as Image Metrics, which has been applied in movies such as The Matrix sequels [6] and The Curious Case of Benjamin Button. The latter used the Mova system to capture a deformable facial model, which was then animated with a combination of manual and vision tracking. [7]
Emerging techniques and research in computer vision are leading to the rapid development of the markerless approach to motion capture. Markerless systems such as those developed at Stanford University, the University of Maryland, MIT, and the Max Planck Institute, do not require subjects to wear special equipment for tracking. Special computer ...
The generation of facial animation data can be approached in different ways: 1.) marker-based motion capture on points or marks on the face of a performer, 2.) markerless motion capture techniques using different type of cameras, 3.) audio-driven techniques, and 4.) keyframe animation. Motion capture uses cameras placed around a subject. The ...
The markerless system allows non-invasive human gait analysis in a natural environment without any marker attachment. Eliminating markers can expand the applicability of human gait measurement and analysis techniques, considerably reduce the preparation time, and enable efficient and accurate motion assessment in all kinds of applications.
Markerless pose tracking. Optical tracking uses cameras placed on or around the headset to determine position and orientation based on computer vision algorithms. This method is based on the same principle as stereoscopic human vision. When a person looks at an object using binocular vision, they are able to define approximately at what ...
Traditionally, character animation has been a manual process. However, poses can be synced directly to a real-life actor through specialized pose estimation systems. Older systems relied on markers or specialized suits. Recent advances in pose estimation and motion capture have enabled markerless applications, sometimes in real time. [25]
X-ray motion analysis is a technique used to track the movement of objects using X-rays. This is done by placing the subject to be imaged in the center of the X-ray beam and recording the motion using an image intensifier and a high-speed camera , allowing for high quality videos sampled many times per second.
