Abstract

This paper presents a fire detection criterion based on flame color, spatial and temporal characteristic analysis of color fire images. To propose the criterion, Firstly the fire candidate regions were selected by using analyzed Cr and Y threshold value, and then texture analysis of candidate regions was performed by using DCT. Finally variation of Y values of these regions was calculated for temporal analysis. The proposed fire detection criterion was simulated by using fifteen test images and practicality was verified.

본 논문에서는 컬러 화재영상에 포함된 화염의 색상 분석과 시공간적 특징 분석을 통하여 신뢰성 높은 화재 판정 조건을 제시한다. 이를 위하여 컬러영상에서 화염을 판정하는 컬러속성으로서 Y-휘도 성분과 Cr-색차 성분을 조합한 문턱치를 도출하고 화염 후보영역을 선정하였다. 선정된 화염 후보영역에 대해서는 화염의 공간적인 질감분석과 시간적인 동적변화를 DCT와 프레임간 휘도성분 변화량을 분석하여 최종 화염 판정 기준으로 제시하였다. 컴퓨터 모의실험을 통하여 제시한 화염 판정 조건의 신뢰성과 실용성을 검증하였다.
