An image processing technique for fire detection in video images

This paper presents an image processing technique for automatic real time fire detection in video images. The underlying algorithm is based on the temporal variation of fire intensity captured by a visual image sensor. The full image sequences are analyzed to select a candidate flame region. Characteristic fire features are extracted from the candidate region and combined to determine the presence of fire or non-fire patterns. Fire alarm is triggered if the fire pattern persists over a period of time. (C) 2006 Elsevier Ltd. All rights reserved.
