More Information
Summary:Provided is a method for extracting facial movement information capable of effectively removing noise. The method for extracting movement information comprises the steps of: obtaining a facial image of a subject; extracting raw data for facial movements from the facial image; detecting macro-movement data from the raw data; and removing a macro-movement component from the raw data to obtain refined micro-movement data. 노이즈의 효과적인 제거가 가능한 움직임 움직임 정보 추출 방법이 제시된다. 움직임 정보 추출 방법은, 피험자의 안면 영상을 획득하는 단계, 상기 안면 영상으로부터 안면 움직임에 대한 원형 데이터(raw data)를 추출하는 단계, 상기 원형 데이터로부터 매크로 움직임 데이터를 검출하는 단계 그리고 상기 원형 데이터로부터 상기 매크로 움직임 성분을 제거하여 정제된 마이크로 움직임 데이터를 얻는 단계;를 포함한다.
