Markerless motion capture is a technology that allows for the recording of human or animal movement without the need for special markers placed on the subject's body or clothing. Instead, it relies on advanced computer vision techniques, often using standard cameras and sophisticated algorithms. These systems analyze video footage to detect and track key body joints and their movements in three-dimensional space.

The core principle behind markerless motion capture involves identifying distinct features on the subject, such as joints, limbs, and facial features. Through machine learning models trained on vast datasets of human movement, the system can infer the pose and motion of the subject from these visual cues. This eliminates the time-consuming and often cumbersome process of attaching and calibrating markers, which can restrict movement and potentially alter the natural performance.

Markerless motion capture finds applications in various fields. In animation and video game development, it enables more realistic character movements and performances. It is also used in sports analysis for studying athletic techniques and identifying areas for improvement. Furthermore, it has potential applications in virtual reality, robotics, and biomechanics research. While highly advanced, the accuracy and robustness of markerless systems can still be influenced by factors like lighting conditions, occlusions, and the complexity of the movement being captured.
