| Abstract(in English) | Early fire detection is one of the important issue of safe operations in extensive facilities such as ports, power plants and large factories. For this purpose, smoke detection with image information is effective. However, smoke detection method has difficulties to treat smoke's information due to its characteristics such as a transmissive property, a non-stationary shape and so on. In this study, we propose a smoke detection method based on its characteristics. Smoke is considers as a fractal, and based on the fractal property, we detect smoke in the images. We use Hurst exponent, which is one of the index of fractals, to detect smoke regions in images. Moreover, as smoke is considered as a moving object, we use time-varying information of smoke in image sequences to obtain more accurate results of the extraction of smoke regions. |
