본문내용

Ⅰ.서론
1. 연구 배경 및 목적
이 논문은 사람의 입모양 ‘아’, ‘이’, ‘오’, ‘음’을 인식하기 위한 방법 제시를 목적으로 한다. 또 이를 구현하
여 응용할 수 있는 게임프로그램을 개발해 입모양의 인식율과 활용방안을 고찰해 본다.
컴퓨터 산업의 발전과 더불어 컴퓨터 인터페이스는 인간에게 보다 친숙한 환경으로 변화해 가고 있다. 친숙
한 환경을 조성하기 위해 최근에는 인간과 컴퓨터의 상호작용(HCI, Human Computer Interaction)에 관한 이
론과 응용에 관련된 학문을 연구가 활발히 진행되고 있다.[1] 이를 통해 인간과 컴퓨터 또는 사이버 공간과의
상호작용에 관련된 현상을 연구하고 발전시킬 수 있다.
사람의 특징 정보나 움직임을 기호화 시키고 이를 인식하는데 있어서 주로 사용한 특징에는 손, 얼굴 등이
있다. 또한 얼굴 내에서는 입모양을 추출하여 시간에 따른 이들의 형태변화에 대한 정보를 추출 할 수 있다.
입 모양 추출 결과는 여러 응용분야에 사용이 가능하다. 예를 들어 음성 인식 분야에서 음성 데이터와 화자의
입 모양 변화를 같이 사용하면 많은 개선을 얻을 수 있음이 알려져 있기 때문에 이에 대한 연구가 많은 관심
을 끌고 있다.[2] 또 얼굴에서 입술은 변화가 가장 심한 부분이기 때문에 입술의 변화를 인식하여 사람의 웃는
모습을 알아내 웃는 얼굴을 촬영한다는 지의 방식은 실제 카메라 기능에도 적용되었다. 그래픽 애니메이션
(animation) 분야에서는 말하는 사람의 변화하는 입 모양을 정확히 추출하여 화자의 입 모양을 보다 쉽게 실
시간으로 생성할 수 있다.
이 연구에 관심을 가지기 시작하면서 실제로 사람의 입모양을 정확히 인식하여 사람의 언어를 이해하는데
한계가 있다는 것을 알게 되었다. 사람의 입술모양의 변화가 같더라도 서로 소리 내는 성질이 다르기 때문이
다. 따라서 입모양의 가장 큰 변화가 있는 ‘아’, ‘이’, ‘오’, ‘음’은 입술의 변화만으로도 인식이 가능하므로 이
네 가지 입모양을 인식하는 것으로 범위를 좁혔다. 이 정보를 특정 파라미터로 제공하면 여러 응용분야에 활
용할 수 있을 것이다.
