Importance Of Facial Animation

I. INTRODUCTION TO FACIAL ANIMATION

The human face is an effective, important and composite communication medium. While a person speaks, the expressions in the face changes frequently. Those expressions are related to both emotions and the flow of speech. It is noted from the studies that speaking is very important for conveying different expressions. Moreover, many psychologists have found out that facial expressions resemble the emotions and attitudes of different people. Hence, in order to improve the systems to produce effective facial expressions, it is important to understand such a language. Computer facial animation is mainly a part of Computer Graphics that binds techniques and models to produce and animate human face and head. It is also associated with the fields like traditional animation and psychology because of its subject type and productivity.

II. DESCRIPTION

A. Importance of Facial Animation

The interest on facial animation has been attained by taking into consideration the importance of human faces in verbal and non-verbal communication and developments in the computer graphics software and hardware. It is also useful in the fields like animated films and computer games, which in turn included areas such as education, entertainment, communication, scientific simulation etc. The improvements of facial animations have begun in 1970s but major enhancements are made in late 1980s.

B. Traditional approaches and related issues

In the present world of computer graphics, there is a need for the improvement of lifelike performers. Initially, flush, fur, muscle, skin, gestures have been successfully devised. Problem arises when it comes to facial expressions and animating them. Traditionally, split-based cameras and...

...hs onto generic meshes. Apart from the novel approach so far, as future work, it would be interesting to build up a database of skin details across different gender, an age and skin type is an open problem. This is important to be applicable on higher-resolution data that contains very small wrinkles and pores. In spite of producing realistic facial animations and many other positive results, there are still many areas that are needed to be studied in order to achieve more accurate and effective results. Here are few areas that require future work: Further studies should be done on how to track expressions in 3D and apply them in Cartesian, on synthesized animation, to improve the picturization of fast movements, To work and concentrate on reducing the time-consumption,, To make the face model react to forces and to make the approach free from self-intersections,
