Abstract

This paper describes an algorithm that can recognize gestures constructing subspace gesture symbols with hybrid feature information. The previous popular methods based on geometric feature and appearance have resulted in ambiguous output in case of recognizing between similar gesture because they use just the Position information of the hands, feet or bodily shape features. However, our proposed method can classify not only recognition of motion but also similar gestures by the partial feature information presenting which parts of body move and the global feature information including 2-dimensional bodily motion. And this method which is a simple and robust recognition algorithm can be applied in various application such surveillance system and intelligent interface systems.

본 논문에서는 다중 혼합 특징 정보를 저 차원 제스처 심볼로 구성하여 제스처를 인식하는 알고리즘에 대해 기술한다. 기존의 기하학적인 특징 기반 방법이나 외관기반 방법에서는 깔, 다리의 위치나 몸의 형상 정보만을 특징 값으로 이용하기 때문에 유사한 신체 동작이나 신체 부위의 움직임에 따라 애매한 결과를 나타내었지만 제안한 방법은 신체의 어느 부위가 움직이는지를 나타내는 부분특징정보(partial feature information)와 전체적인 신체의 형상을 표현하는 전역특징정보(global feature information)를 이용함으로써 동작의 구분뿐만 아니라 유사한 동작을 인식할 수 있는 장점이 있다. 그리고 비교적 적은 계산량과 높은 인식률 때문에 감시 시스템이나 지적 인터페이스 시스템 같은 여러 응용 분야에 적용될 수 있다.
