3D FACE MODEL RECONSTRUCTION BASED ON STRETCHING ALGORITHM
In order to get realistic face model,face model reconstruction is a very important process,we need a way to map the two-dimensional face image coordinate to standard face model,so we propose a general face model reconstruction process based on stretching algorithm which including three stage.In the pose recovery stage,the pose recovery formulation is based on the non-linear least squares structure-from-motion algorithm.In the face partial point adjustment stage,which we define the stretching coefficient to adjust the feature point and non-feature point separately.After we make the face point in the right position for the model,from scattered data interpolation stage which based on the radial bases functions we can get a general function to calculate accurate 3D face model coordinates.Compared with other algorithm,the stretching algorithm can improve the accuracy of a three-dimensional map from the standard face model to a specific human face.
