Reconstruction Of A 3d Human Head Model From Images

The main aim of this thesis is to generate 3D models of human heads from
uncalibrated images. In order to extract geometric values of a human head,
we find camera parameters using camera auto calibration. However, some image
sequences generate non-unique (degenerate) solutions. An algorithm for
removing degeneracy from the most common form of camera movement in face
image acquisition is described. The geometric values of main facial features are
computed initially. The model is then generated by gradual deformation of a
generic polygonal model of a head. The accuracy of the models is evaluated
using ground truth data from a range scanner. 3D models are covered with
cylindrical texture values obtained from images. The models are appropriate for
animation or identification applications.
