초록
리바이저 시스템은 프로젝션 화면 상에서 종이 문서의 수정시 사용되는 교정 제스처와 동일한 제스처를 이용한 온라인 문서 교정 시스템이다. 이를 위해, 프로젝션 화면 상에서 손이나 문서와 같은 전경물체추출 기술과 연속 동작으로 부터의 제스처 인식 기술이 필요하다. 많은 조명 변화와 복잡한 배경 상에서 전경물체를 검출하기 위해서 기하보정과 색상보정을 수행하고, HMM 기반 제스처 인식기를 구현하였다. 실험 결과로부터 연속 제스처에서 93.22%의 인식률을 나타남을 볼 수 있다.
Abstract
TheReviser is a digital document revision application on a projection display, which allows us to interact a digital document with the same gestures used for paper documents revision. To enable these interactions, TheReviser should detect foreground objects such as hands or pens on a projection display, and should spot and recognize gesture commands from continuous movements of a user. To detect foreground objects from a complex background in various lighting conditions, we perform geometry and color calibration between a captured image and a frame buffer image. TheReviser uses an HMM-based gesture recognition method. Experimental results show that the proposed application recognizes user’s gestures on average 93.22% in test gesture sequences.
