| Research Abstract |
The achievements of our research during last three years are listed as followings.
1. Basic design of the system of analyzing and synthesizing inases of facial expressions.
In the first place, the architecture of the system was examined. Secondly, softwares including ones for image processing and computer graphics to be necessary for developing the system were implenented into the graphic work station. Then, the method of systematic descriptions of inases of face, and facial expressions in terns of knowledge-based lmase codins approach developed by this head investigator and his co-workers. As a result, the advantage of the knowledge-based inase coding approach was verified.
2. Development of application softwares for analyzing iiiages of facial expressions.
The software of detecting the head notion and extracting parameters of shape concerning expressions was developed.
3. Development of application softwares for synthesizing images of facial expressions.
To synthesize natural images of facial expressions only in terms of parameters of shape concerning expressions, the way of deforming a model of face of the system was examined from psychological point of view, so that it can simulate real facial actions. Consequently, based on FACS, the generation rules for synthesizing images of facial expressions were constructed.
4. Psychological Assessment
Extracted facial parameters of expressions and synthesized images of facial expressions were assessed by the psychological experiments. As a result, the validity of our developmental system of analyzing and synthesizins images of facial expressions were confirmed.
5. Examination of the application of our' system for the researches in Psychology and Behay ioral Science.
Significant researches on facial expressions and nonverbal communication in Psychology and Behavioral Science were surveyed. And the role of our developmental svstell to take in those research areas was examined.
