Abstract
An automatic 3D modeling system and method are described in which a 3D model may be generated from a picture or other image. For example, a 3D model for a face of a person may be automatically generated. The system and method also permits gestures/behaviors associated with a 3D model to automatically generated so that the gestures/behaviors may be applied to any 3D models.

determining the boundary of the object to be modeled;
determining the location of one or more landmarks on the object to be modeled;
determining the scale and orientation of the object in the image based on the location of the landmarks;
aligning the image of the object with the landmarks with a deformation grid;
and generating a 3D model of the object based on the mapping of the image of the object to the deformation grid.
determining the boundary of the object to be modeled;
determining the location of one or more landmarks on the object to be modeled;
