The quest of developing realistic facial animation is ever-growing. The
emergence of sophisticated algorithms, new graphical user interfaces, laser scans and
advanced 3D tools imparted further impetus towards the rapid advancement of
complex virtual human facial model. Face-to-face communication being the most
natural way of human interaction, the facial animation systems became more
attractive in the information technology era for sundry applications. The production of
computer-animated movies using synthetic actors are still challenging issues.
Proposed facial expression carries the signature of happiness, sadness, angry or
cheerful, etc. The mood of a particular person in the midst of a large group can
immediately be identified via very subtle changes in facial expressions. Facial
expressions being very complex as well as important nonverbal communication
channel are tricky to synthesize realistically using computer graphics. Computer
synthesis of practical facial expressions must deal with the geometric representation
of the human face and the control of the facial animation. We developed a new
approach by integrating blend shape interpolation (BSI) and facial action coding
system (FACS) to create a realistic and expressive computer facial animation design.
The BSI is used to generate the natural face while the FACS is employed to reflect the
exact facial muscle movements for four basic natural emotional expressions such as
angry, happy, sad and fear with high fidelity. The results in perceiving the realistic
facial expression for virtual human emotions based on facial skin color and texture
may contribute towards the development of virtual reality and game environment of
computer aided graphics animation systems. |
