Abstract
The flame recognition system based on video image is applied to the fire flame detection, and it can be very good to avoid the shortage of the traditional fire flame detection system. Three frame difference algorithm is adopted to extract the motion features of the flame. And Lab color space is applied in analyzing the flame color. By analyzing the circular degree of the flame and the interference sources, the change rate of the flame area and the angle feature of the fire flame, it can be determined whether there is a fire in the image. The experimental results shows: this algorithm can not only effectively improve the accuracy and real-time performance of the flame detection and identification, but also eliminate the interference of other substances and reduce the misjudgment.
