Abstract
In this paper, we propose an efficient method for recognizing lip. Lip is localized by using the shape of lip and the pixel values around lip contour. The shape of lip is represented by a statistically based active shape model which learns typical lip shape from a training set. Because this model is affected by the initial position, we use a boundary between upper and lower lip as initial position for searching lip. The boundary is localized by using a weighted vector based on lip's shape. The experiments have been performed for many images, and show very encouraging result.

능동적 형태 모델과 가중치 벡터를 이용한 입술 인식
장경식 (동의대학교 멀티미디어공학과)
Abstract
이 논문은 입술의 형태와 입술 외곽선 부근의 화소값을 이용하여 입술을 효과적으로 인식하는 방법을 제안하였다. 입술의 형태는 학습 영상을 통계적으로 분석하는 능동적 형태 모델을 기반으로 구성하였다. 이 방법은 탐색시 초기 위치의 영향을 받기 때문에 이 논문에서는 입술의 형태에 기반한 가중치 벡터를 이용하여 두 입술 사이의 경계선을 찾고 탐색의 초기 위치로 사용하였다. 다양한 입술 영상들을 대상으로 실험하여 좋은 결과를 얻었다.
