Separating shape and pose variations

Full text not available from this repository.


We have integrated a coupled-view Flexible Shape Model (FSM) and the Linear Combination of Views (LCV) technique to form an Integrated Shape and Pose Model (ISPM) of a 3D deformable object. The ISPM describes the object's intrinsic shape variations via the coupled-view FSM, while modelling its extrinsic pose variations via the LCV technique, all in a 2D image context. This enables us to model pose and shape independently in 2D. Our main contribution is the pose-alignment algorithm that separates pose and shape information. Some preliminary results are provided.
