VERFAHREN UND EINRICHTUNG ZUM ERKENNUNG VON FASERN AUF DER GRUNDLAGE VON BILDANALYSE

摘要

Method for automatically detecting fires, based on flame and/or smoke recognition by analyzing a sequence of images. The analysis is based on several image processing algorithms. One algorithm consists in comparing the frequency content of at least an image of said sequence with the frequency content of a reference image so as to detect an attenuation of high frequencies independently of variations on other portions of the spectrum.
