초록

본 논문에서는 얼굴영역에 존재하는 특정영역인 분할된 머리, 이마, 눈, 귀, 코, 입, 턱의 슈퍼 상태에서 임베디드 데이터를 이용하여 얼굴인식 방법을 제안한다. 제안된 방법에서는 정규화된 크기(92×112)에서 특정영역인 슈퍼 상태를 정의하고, 분할된 슈퍼 상태의 내부요소인 임베디드 데이터만을 추출하여 PCA 알고리듬으로 얼굴인식을 수행한다. 제안된 방법에서는 원래영상을 모두 학습하는 것이 아니라 분할된 임베디드 데이터만을 학습시키기 때문에 제안된 영상의 크기(92×112)에서 특정 데이터를 받아들일 수 있다. 그리고 평균적으로 92×112 크기의 영상에서는 99.05%, 단계1은 99.05%, 단계2는 98.93%, 단계3은 98.54%, 단계4는 97.85%의 얼굴인식률을 보였다. 따라서 실험을 통하여 제안된 방법은 얼굴영상의 정보를 축소할 뿐만 아니라 처리속도도 향상됨을 보였다.

In this paper, we propose face recognition method using embedded data in super states segmentalized that is specification region exist to face region, hair, forehead, eyes, ears, nose, mouth, and chin. Proposed method defines super states that is specification area in normalized size (92×112), and embedded data that is extract internal factor in super states segmentalized achieve face recognition by PCA algorithm. Proposed method can receive specification data that is less in proposed image's size (92×112) because do orignal image to learn embedded data not to do all loaming. And Showed face recognition rate in image of 92×112 size averagely 99.05%, step 1 99.05%, step 2 98.93%, step 3 98.54%, step 4 97.85%. Therefore, method that is proposed through an experiment showed that the processing speed improves as well as reduce existing face image's information.
