The paper presents a fire/flame detection method based on color analysis of fire image. Afire video clip was analyzed under the proposed algorithm to detect the fire region. First the image is converted into HSI color model and then the color mask is created and applied on the original image to detect the fire/flame regions. To remove the spurious noise, image difference method is used and further images are transformed into gray scale and average filter is applied on images to eliminate weaken

... spurious fire regions. Thresholding is performed to remove the spurious fire completely. Finally, the burning degree is calculated using a simple method that is based on white pixel ratio. The proposed approach is tested on a video of fire and the results obtained are positive. On an Intel i3 processor with 3GB RAM, fire signal was received within three seconds.
