Abstract

In this paper, we propose the face recognition method combining the ECSP preprocessing technique which is modified version of previous CS-LBP and the illumination-robust D2D-PCA feature. The performance evaluation of proposed method was carried out using various binary pattern operators and feature extraction algorithms such as well-known PCA and 2D-PCA on the Yale B database. As a results, the proposed method showed the best recognition accuracy compared to different approaches, and we confirmed that the proposed approach is robust to illumination variation.

본 논문에서는 기존의 CS-LBP를 변형한 ECSP 전처리 기법과 조명에 강인한 D2D-PCA 특징을 결합하는 얼굴인식 방법에 대하여 제안한다. 제안하는 얼굴인식 방법의 성능평가는 Yale B 데이터베이스 상에서 기존의 다양한 이진패턴 변환 영상과 얼굴인식에 널리 사용되고 있는 PCA 및 2D-PCA 특징을 이용하여 수행되었다. 실험 결과, 제안하는 얼굴인식 방법은 다른 방법들에 비하여 가장 높은 인식 성능을 보였으며, 이로부터 제안 시스템이 조명 변화에 강인한 얼굴인식 방법임을 확인하였다.
