Detecting video phenomena, such as fire in an aircraft cargo bay, includes
receiving a plurality of video images from a plurality of sources,
compensating the images to provide enhanced images, extracting features
from the enhanced images, and combining the features from the plurality
of sources to detect the video phenomena. The plurality of sources may
include cameras having a sensitivity of between 400 nm and 1000 nm and/or
may include cameras having a sensitivity of between 7 and 14 micrometers.
Extracting features may include determining an energy indicator for each
of a subset of the plurality of frames. Detecting video phenomena may
also include comparing energy indicators for each of the subset of the
plurality of frames to a reference frame. The reference frame corresponds
to a video frame taken when no fire is present, video frame immediately
preceding each of the subset of the plurality of frames, or a video frame
immediately preceding a frame that is immediately preceding each of the
subset of the plurality of frames.
