Abstract: Inferring both 3D structure and motion of nonrigid objects from monocular images is an important problem in computational vision. The challenges stem not only from the absence of point correspondences but also from the structure ambiguity. In this paper, a hierarchical method which integrates both local patch analysis and global shape descriptions is devised to solve the dual problem of structure and nonrigid motion recovery by using an elastic geometric model---extended superquadrics. The... (Update)

...model which can model details of human faces and is proven to be very useful for both 3D head motion recovery and visualization. In [33], extended superquadrics were used as global motion models in order to track both structure and nonrigid motion of elastic objects such as...
