- Abstract
- Through facial expressions, it is able to read the human emotions. In order to achieve a smooth interaction between human and machines, the importance of emotion recognition is increasing. In this paper, we do handle human internal states except the existing basic six human emotions. To indicate a change of the feature points of face, we use vector chain code encoding method, it is extended from the existing chain code method. The chain code only encode the direction information between features. The vector chain code can encode the direction information and distance information altogether. Through experiments, a method utilizing a vector chain code that presented in this paper was more improved rather than the method using the conventional chain code.
