Flame Pattern
SigniFire™ constantly monitors
incoming video frames first applying a patented Digital Signal
Processing (DSP), and
secondly using Artificial Intelligence (AI) to recognize flame specific
patterns and signatures.
DSP Stage
The objective of the DSP stage is to split
monochromatic video image into two channels -- RED and BLUE. These names
have nothing to do with real colors of the original image. The RED image
is produced by applying a lo-pass filter to brightness values of the
original video sequence. The BLUE image is produces by applying a hi-pass
filter, thus highlighting pixels that have higher rates of change in
their brightness. Open flames generate a very distinctive pattern
with a bright red core and blue corona.
Artificial Intelligence Stage
SigniFire™ deploys advanced neural networks algorithms
to search the video images for specific patterns, representative of flames.
The network has been trained on over 10,000 samples of flames and nuisance
sources. The system is able to discriminate
between flames and other light sources with high degree of
reliability.
In the video that is transmitted by the SigniFire™ system flames are shown highlighted by red rectangle to make a remote
operator aware of the location the system has detected a flame source.
