Human face representation by means of polynomial expansion of the harmonic descriptors of tomograms.
A method is presented to obtain realistic modifications of faces represented as sequences of tomograms, to be used for geometrical modelling or for planning of plastic surgery. This method uses a mathematical model consisting of the harmonic expansion of tomograms whose harmonic parameters are represented by cubic spline functions of the z variable. Based on this model a three dimensional shape editor is proposed that allows for local modifications. The results obtained using tomograms of a plaster mould are presented.
