Abstract

It is Face recognition is a very important process in image monitoring and it is a form of biometric technology. The recognition process involves many variables and is highly complex, so the software development has only begun recently with the development of hardware. Face detection technology using the CCTV is a process that precedes face analysis, and it is a technique that detects where the face is in the image. Research in face detection and recognition has been difficult because the human face reacts sensitively to different environmental conditions, such as lighting, color of skin, direction, angle and facial expression. The utility and importance of face recognition technology is coming into the limelight over time, but many aspects are being overlooked in the facial area detection technology that must precede face recognition. The system in this paper can detect tilted faces that cannot be detected by the AdaBoost detector and It could also be used to detect other objects.

얼굴검출 과정은 영상 모니터링에서 매우 중요한 과정이며 생체 인식 기술의 한 종류이다. 검출과정은 변수가 많고 복잡하여 하드웨어가 발전하고 있는 근래에 와서 소프트웨어적인 발전이 이루어지고 있다. CCTV를 이용하는 분야 중 얼굴 검출 기술은 얼굴을 분석하기 이전에 실행되는 과정으로 영상에서 얼굴이 있는 곳을 찾아내는 기술이다. 사람의 얼굴은 조명이나 피부 색, 방향과 각도, 표정 등 여러 가지 환경적 조건에 따라 민감한 반응을 하기 때문에, 얼굴 검출에 관한 연구는 많은 어려움이 있다. 얼굴 검출 기술의 활용성과 중요성은 시간이 지날수록 각광받고 있으나, 얼굴 검출 이전에 선행되어야 하는 얼굴 영역 검출 기술에 대해서는 간과하는 측면이 많다. 본 논문의 시스템은 AdaBoost detector에서 검출 못하는 기울어진 얼굴을 검출할 수 있어 다른 사물의 검출도 같은 기술을 사용할 수 있을 것이다.
