1. A method of detecting fire using video analysis, the method comprising:

  • acquiring video data comprised of individual frames;

    dividing each of the individual frames into a plurality of frame elements;

    calculating a structural feature associated with each frame element;

    identifying a core region of fire based on the calculated structural features;

    defining a region surrounding the core region;

    calculating a temporal feature associated with each frame element within the surrounding region;

    associating the temporal features calculated with respect to frame elements within the surrounding region with the identified core region by assigning a representative temporal feature value to the core region; and

    generating an output indicating whether the analyzed video data indicates the presence of fire based, at least in part, on the structural features and assigned temporal features associated with the identified core region.
