摘要
In a flame identification method and device for identifying any flame image in a plurality of frames captured consecutively from a monitored area, for each image frame, intensity foreground pixels are obtained based on intensity values of pixels, a fire-like image region containing the intensity foreground pixels is defined when an intensity foreground area corresponding to the intensity foreground pixels is greater than a predetermined intensity foreground area threshold, and saturation foreground pixels are obtained from all pixels in the fire-like image region based on saturation values thereof to obtain a saturation foreground area corresponding to the saturation foreground pixels. Linear regression analyses are performed on two-dimensional coordinates each formed by the intensity and saturation pixel areas associated with a corresponding image frame to generate a determination coefficient. Whether a flame image exists in the image frames is determined based on the determination coefficient and a predetermined identification threshold.
