Markerless motion capture

Definition

Markerless motion capture is a technology that enables the recording of human movement without the use of physical markers attached to the subject's body. This technique relies on advanced computer vision and machine learning algorithms to analyze and interpret the movements of the subject in real-time, capturing their actions in a virtual environment. By eliminating the need for markers, this approach allows for greater freedom of movement and ease of use in various applications such as film production, video games, and animation.
