초록

4D 영화는 3D 혹은 일반영상과 함께 물리적인 효과를 추가한 영화이다. 시청자에게 물리적 효과를 제공하기 위해선 각 장면마다 적용할 물리 효과 데이터를 작성해야 한다. 본 논문에서는 영화의 폭발 장면이나 빙설, 적설 장면의 상황을 판단하여 효율적으로 물리효과를 제공할 수 있는 영상 검출 시스템을 제안한다. 제안하는 영상 검출 시스템은 R컬러와 적색차 정보인 $C_r$값을 이용한 화염 검출 알고리즘과 RGB 컬러를 이용한 적설 영역 검출 알고리즘, 8051 계열의 MCU를 사용한 제어시스템으로 구성된다. 성능평가 결과 화염의 경우 91%의 검출율을 보였으며, 적설 영역의 경우 26%의 오검출이 발생하였다. 또한 해당 알고리즘을 통한 자동적인 물리적 효과 제공이 가능함을 보였다.

4D film is just a film that made by adding some physical effects to 3D film or general film. In order to provide physical effects to the audience, the data that make the physical effect must be added to each frames. In this paper, we proposed a video detection system that can efficiently provide physical effects by assessing the present situation such as explosion scene, snowing scene. The proposed video detection system contains an algorithm for fire detection by using R color and $C_r$ value, and also an algorithm for snow detection by using RGB color model. The system constitutes in a MCU that from 8051 family. In the performance evaluations, the result shows that 91% of detection rate in case of fire and 25% of false detection rate in case of snow. Also the system is capable of providing physical effects automatically.
