Fig. 3From: A Review of the Evolution of Vision-Based Motion Analysis and the Integration of Advanced Computer Vision Methods Towards Developing a Markerless SystemExample of a poseable skeleton model. “Bones” of a pre-specified length are connected at joints, and rotation of the bones around these joints allows the skeleton to be posed. The skeleton model is commonly fit to both marker-based motion capture data and computer vision-based markerless systemsBack to article page
