Abstract: A digital image having a plurality of pixels is analyzed to detect a fire condition. A first color parameter is determined from image color values of pixels of the image. A plurality of fuzzy membership functions correlated to image colors are defined, the plurality of fuzzy membership functions including a first fuzzy color membership function having a trend defined by said first color parameter. A fuzzy inference procedure is applied to pixels of the image to determine whether a fire condition is indicated by the digital image.
