Template model and scanned point cloud Posture fitting Shape fitting Joint correction Texture 32 simultaneously triggered DSLR cameras. The point cloud is computed by multi-view stereo reconstruction. 28 corresponding landmarks (red dots) are manually selected on template model and point cloud. The template model can be animated by its skeleton. By template fitting we transfer this attribute to the scan. Rigid registration alternating with inverse kinematics This step scales, rotates and

Non-linear optimization with three energy terms After the fitting procedure the joints of the skeleton are not in the correct position anymore. This is corrected by exploiting generalized barycentric coordinates. Landmarks Point-to-point Regularization
