Proposed Approach

• Mesh deformation to capture variability in body
  shape.
• Fitting a template mesh to video data
• - register the mesh to visual hull

Proposed Approach

• Mesh deformation to capture variability in body
  shape.
• Fitting a template mesh to video data
• - register the mesh to visual hull
• Compute a skeleton corresponding to the deformed
  mesh.
• - pose deformation transfer
  between original mesh and the deformed mesh
