Patent Images
1. A method, comprising:
- computing a first color parameter based on a set of image color values of pixels of a digital image;
defining a plurality of fuzzy membership functions correlated to image colors, said plurality of fuzzy membership functions comprising a first fuzzy color membership function having a trend defined by said first color parameter;
applying to a current pixel of the digital image a fuzzy inference procedure based on said plurality of fuzzy membership functions; and
classifying the current pixel as a fire image pixel based on the applying of the fuzzy inference procedure to the current pixel.

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.

17. A system, comprising:
-
one or more memories; and processing circuitry, which, in operation determines a first color parameter based on image color values of a set of pixels of a digital image; defines a plurality of fuzzy membership functions correlated to image colors, said plurality of fuzzy membership functions comprising a first fuzzy color membership function having a trend defined by said first color parameter; applies a fuzzy inference procedure to pixels of the set of pixels based on said plurality of fuzzy membership functions; and classifies pixels of the set of pixels as fire image pixels based on the applying of the fuzzy inference procedure to the pixels of the set. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
