Facial Expression Morphing and Animation with Local Warping Methods
نویسندگان
چکیده
In this paper, we applied local warping techniques to construct a frame work of image-based morphing for facial expressions animation with low complexity. From the experience we obtained in various spatial transformations, the local warping methods are more adequate for facial expressions morphing. We utilized two transformations that can deal with local deformations: piecewise polynomial transformation and radial basis function transformation. The simulation results are satisfactory. The facial warping techniques could be applied to various applications, such as face recognition, authentication, dynamic imagery, speech (action) semantic animation, multimedia and virtual reality construction, low-bandwidth video conference image transmission, and intelligent man-machine interface.

متن کاملSynthesis of human facial expressions based on the distribution of elastic force applied by control points
Facial expressions play an essential role in delivering emotions. Thus facial expression synthesis gain interests in many fields such as computer vision and graphics. Facial actions are generated by contraction and relaxation of the muscles innervated by facial nerves. The combination of those muscle motions is numerous. therefore, facial expressions are often person specific. But in general, f...
