Fig. 4From: A Review of the Evolution of Vision-Based Motion Analysis and the Integration of Advanced Computer Vision Methods Towards Developing a Markerless SystemSum of Gaussian body model from Stoll [75]. A skeleton (left) forms the foundation of the model, providing limb-lengths and body pose. The body is given volume and appearance information through the use of 3D Spatial Gaussians arranged along the skeleton (represented by spheres). The resulting information allows the model to be fit to image dataBack to article page
