Drawing human faces using words and conceptual fuzzy sets

In this paper, we propose an interactive drawing system for human faces belonging to different races. The system has an average face of each race, generated using anthropometry measurements of the face and the head. The average face is shown to the user as an initial face which is then transformed to the desired face using linguistic expressions describing facial features. Since the meaning of those expressions depends on the race of the user, the meaning of a word is computed using conceptual fuzzy set (CFS). CFSs can represent context dependent meaning. The context here is the race. Experiments show that the proposed approach can adapt the meaning of the words according to the race of the users.
