사상체질 판별을 위한 측면 얼굴 이미지에서의 특징 검출 = Side Face Features` Biometrics for Sasang Constitution

다국어 초록 (Multilingual Abstract)

There are four types of human beings according to the Sasang Typology. Oriental medical doctors frequently prescribe healthcare information and treatment depending on one`s type. The feature ratios (Table 1) on the human face are the most important criterions to decide which type a patient is. In this paper, we proposed a system to extract these feature ratios from the people`s side face. There are two challenges in acquiring the feature ratio: one that selecting representative features; the other, that detecting region of interest from human profile facial image effectively and calculating the feature ratio accurately. In our system, an adaptive color model is used to separate human side face from background, and the method based on geometrical model is designed for region of interest detection. Then we present the error analysis caused by image variation in terms of image size and head pose. To verify the efficiency of the system proposed in this paper, several experiments are conducted using about 173 korean`s left side facial photographs. Experiment results shows that the accuracy of our system is increased 17.99% after we combine the front face features with the side face features, instead of using the front face features only.
