Detection Algorithm

The proposed video-based fire detection algorithm consists of four steps: (i) moving pixels or regions in the current frame of a video are determined, (ii) colors of moving pixels are checked to see if they match to pre-specified fire colors, then wavelet analysis in (iii) temporal and (iv) spatial domains is carried out to determine high-frequency activity within these moving regions. In the following subsections, each step of the proposed algorithm is explained in detail.
