"Head Modeling with Camera Auto-calibration and Deformation", 2002.http://hdl.handle.net/20.500.12416/7661A 3D head modeling method from a sequence of 2D images is described. The views from which the input images are acquired are not calibrated. Therefore, an auto-calibration method for a sequence of images with small rotations and translation is developed. For this purpose, we have modified an already existing auto-calibration algorithm to incorporate known aspect ratio and skew values to make it applicable for small rotation around a single axis. We apply this auto-calibration technique to head (face) modeling. Three dimensional positions of known facial features computed from two dimensional images are used to deform a generic head model by using a spring based energy minimization method.eninfo:eu-repo/semantics/closedAccessConference Object
