For early fire detection, smoke is considered as an important sign for it. Image based detection methods more useful than other methods which use some special sensor devices because of the cost and difficulties in setting them around target areas. When treating the image information of smoke, it is important to consider characteristics of smoke such as the semi-transparency, the non-stationary shape...
In this paper, a multi scale Gaussian edge detector is constructed. According to transfer properties across scales of the wavelet modules of the signal edge and the noise edge, we combine the properties of edges in different scales and propose a multi scale edge fusion algorithm consisting of edge transfer, edge inherit and edge growth. The edge is an important content of obtaining information of...
