  • Abstract This thesis is devoted to generating the boundary of face profile for face transformation in face combining, face resembling and face recognition. The face reformation can be carried by the geometric, harmonic model and numerical
    methods, such as the splitting shooting method(SSM) and the splitting integrating methods(SIM) of image transformation. However, the harmonic model needs the boundary correspondence
    in the Dirichlet condition. It is forbidding to
    depict the pixel-pixel correspondence, but is necessary to find a few important, charactistic
    point-point correspondences. Hence, we may seek the blending curves to establish the curve-curve correspondence. In this thesis, the formulation for the face boundary and profiles are explored by three methods: cubic spline, quadratic, spline, and the ordinary differential equation(ODE) approaches using Hermite interpolation. The latter is advantageous for handling different
    boundary conditions in 2D clamped, simply support conditions and given curvature. The combined algorithms using both cubic splines
    and the ODE methods are also developed. New mathematical algorithms of curves for given curvature on the boundary are proposed in this thesis, and the number of nonlinear equations
    involved in curvature conditions can be reduced to two or three only. This thesis also displays the validity of the ODE approaches for 2D curves.
    Graphical experiments are carried out to resembling face images of a young girl, based on the photos of her parents and her childhood.
