Abstract: Abstract: The existing image fire detection algorithms have the problems of weak generalization ability, high false alarm rate, and low practicality. Based on four advanced object detection convolutional neural networks (e.g. Faster-RCNN, R-FCN, SSD and YOLO v3), new image fire detection algorithms were developed. The comparison of the proposed and current algorithms reveals that the algorithms based on object detection CNNs have significant advantages. Especially, the average precision of the algorithm based on YOLO v3 reaches to 84.5%, and the detection velocity is 28 frame/s. Besides, the YOLO v3 also has stronger robustness of detection performance, and is suitable for developing fire detection system.
