움직임분석 및 색상정보를 이용한 실시간 얼굴추적 = Realtime Face Tracking using Motion Analysis and Color Information

국문 초록 (Abstract)

동영상으로부터 움직임 분석 및 색상정보를 이용한 실시간 얼굴 추적 방법을 제안한다. 시간미분연산에 의하여 실시간으로 입력되는 동영상으로부터 움직임 영역을 검출한 후, 컬러공간 융합 필터링에 의하여 얼굴 영역 후보 화소를 검출하고 눈, 입등 얼굴 구성 요소 검출에 의하여 얼굴 영역의 실시간 추적을 행하였다. 얼굴 구성요소의 참조 템플릿을 구축한 후 신규 입력되는 연속영상의 얼굴 영역으로부터 템플릿 매칭을 행함으로써 추출된 얼굴 영역의 신뢰도를 판정하는 방법으로 얼굴 영역 추적의 안정도를 향상시켰다.

A realtime face tracking algorithm using motion analysis from image sequences and color information is proposed. Motion area from the realtime moving images is detected by calculating temporal derivatives first, candidate pixels which represent face region is extracted by the fusion filtering with multiple color models, and realtime face tracking is performed by discriminating face components which includes eyes and lips. We improve the stability of face tracking performance by using template matching with face region in an image sequence and the reference template of face components.
