Morphing technique of human face image is a key technique in the field of face modelization. Based on geometrical feature of facial contour

this paper selects appropriate Feature Points and constructs a component feature mesh model adapted to face image morphing through the muscle movement principle of face organs. In order to imitate the muscle movement of facial component

such as eye

nose

brow

mouth and face contour

feature mesh constitutes two kind of synthetic muscle. One is the contour muscle which manipulates the removal of vertical direction. Another is the linear muscle that controls the displacement of horizontal direction. Thus

the movement of muscle point can be divided into two directions

vertical and horizontal

which is controlled respectively by the contour muscle and linear muscle where the point locates. Feature mesh model ensures that facial component morphing is manipulated in virtue of the change of component contour

coinciding with psychological cognition. This makes it more adapted to human image morphing than other morphing algorithms. The result of experiment shows that the facial images which generated by this algorithm are accurate

and the expression effects are more natural.
