摘要
Conventional fire detection systems use physical sensors to detect fire Chemical properties of particles in the air are acquired by sensors and are used by conventional fire detection systems to raise an alarm However, this can also cause false alarms, for example, a person smoking in a room may trigger a typical fire alarm system In order to manage false alarms of conventional fire detection systems, a computer vision-based fire detection algorithm is proposed in this paper The proposed fire detection algorithm consists of two main parts fire color modeling and motion detection The algorithm can be used in parallel with conventional fire detection systems to reduce false alarms It can also be deployed as a stand-alone system to detect fire by using video frames acquired through a video acquisition device A novel fire color model is developed in CIE L*a*b* color space to identify fire pixels The proposed fire color model is tested with ten diverse video sequences including different types of fire The experimental results are quite encouraging m terms of correctly classifying fire pixels according to color information only The overall fire detection system's performance is tested over a benchmark fire video database, and its performance is compared with the state-of-the-art fire detection method
