Abstract

This paper proposed the face recognition method which can be effectively applied to the robot's vision system. The proposed algorithm is recognition using hue extraction and feature point. hue extraction was using difference of skin color, pupil color, lips color. Features information were extraction from eye, nose and mouth using feature parameters of the difference between the feature point, distance ratio, angle, area. Feature parameters fuzzified data with the data generated by membership function, then evaluate the degree of similarity was the face recognition. The result of experiment are conducted with frontal color images of face as input images the received recognition rate of 96%.

본 논문에서는 로봇의 시각시스템에 효과적으로 적용할 수 있는 얼굴인식 방법을 제안하였다. 제안한 알고리즘은 얼굴영상의 색상추출과 특징점을 이용하여 인식한다. 색상추출은 피부색, 눈동자색, 입술색의 차를 이용하였으며, 특징정보는 눈, 코, 입에서 추출된 특징점 사이의 거리, 거리 비율, 각도, 면적의 차를 특징 파라미터로 이용하였다. 특징 파라미터를 퍼지화 데이터로 멤버십 함수를 생성한 후, 유사도를 평가하여 얼굴을 인식하였다. 입력받은 정면 칼라 영상으로 실험한 결과 96%의 인식율을 나타내었다.
