CHAPTER 4. SHORT RANGE SMOKE DETECTION IN VIDEO 67Table 4.2: Smoke and flame detection time comparison of Method-4.1 andMethod-4.3, respectively. Smoke is an early indicator of fire. In Movies 11 and12, flames are not in the viewing range of the camera.Video Method Detection time DescriptionSequences(sec.)Movie 10 Method-4.1 3 Fire in a gardenMethod-4.3 8Movie 11 Method-4.1 4 Fire in a trash binMethod-4.3 N/AMovie 11 Method-4.1 7 Fire at a distance of 30mMethod-4.3 N/Acontour analysis of possible smoke regions. These regions are then analyzedalong with their corresponding background regions with respect to their RGBand chrominance values. The turbulent behavior of smoke is also modeled withMarkov models and set as an additional clue for the final smoke decision.The method can be used for detection of smoke in movies and video databasesas well as real-time detection of smoke. It can be incorporated with a surveillancesystem monitoring an indoor or an outdoor area of interest for early detection offire. It can also be integrated with the flame detection method in [87] in order tohave a more robust video based fire detection system.
