Abstract

Methods and computer program code computer program codes for modifying an expression of an actor in at least one video frame based on performance of the actor in a sequence of frames of video footage. A plurality of control points are identified for characterizing the shape of the actor in each frame of the video footage by a shape vector comprising positions of the control points. The shape vectors of each frame are then warped to a common standard frame thereby generating an aligned shape vector and a transformed image for each frame. The aligned shape vectors and attendant texture vectors are transformed in accordance with specified pose and expression parameters to create new shape and texture vectors which are reinserted into the sequence of frames so as to reanimate the actor.
