This paper presents a fire detection algorithm based on frequency analysis of infrared images. In the proposed algorithm, Firstly the candidate regions are separated by using pre-defined brightness value, and then fourier analysis is performed for these regions of successive infrared thermal images. Finally, The variation of frequency components are evaluated and the fire regions are decided. The proposed algorithm is simulated by Matlab and we verified practicality of the algorithm.
