A Dynamic Component Deforming Model for Face Shape Reconstruction

A novel method, called dynamic component deforming model, is proposed to reconstruct the face shape from a 2D image based on feature points. Assuming that human face belongs to a linear class, principal components learned from a 3D face database are used in order to constrain the results. Different from the fixed components used in the traditional methods, the significance of each component is investigated while the most correlative ones are selected as the basic space. This novel representation is able to fit a more exact 3D shape for an individual than the known methods as the useless data are excluded. Comparison results show that the proposedmethod achieves good results on both contrived data with known ground truth together with real photographs.
