In this paper, we propose a deep learning based smoke detection method which overcomes drawbacks of the conventional smoke detection method. Real-time smoke detection via machine-based identification method in the area of surveillance system has been of great advantage in recent era. An effective smoke detection strategy is necessary to avoid the hazard resulting from fire. The conventional smoke detection method lacks in accuracy, therefore, deep learning based smoke detection is adopted for the same purpose. However, a lot of video smoke detection approach involves minimum lighting and it can be required for the cameras to discover the existence of smoke particles in a scene. Eliminating such challenges, our proposed work introduces a novel concept like hybrid reinforcement deep Q learning classifier of smoke detection. This work takes the correct decision about the smoke particles via reinforcement deep Q learning and classifies the smoke particle with the deep convolutional neural network. The proposed real-time algorithm is aimed to provide proper education for the engineers to detect moving objects for the purpose of developing surveillance systems. This method is also helpful for the beginners who have keen interest in the field of deep learning to control fire. Here, to observe the temporal variance of fire smoke, spatial analysis is identified in the present frame and in the subsequence of the video, spatio-temporal analysis has been taken into account. Finally, smoke particles are classified with the novel reinforcement Q learning-based classifier and experimental results show a better performance regarding classification accuracy. So we can detect smoke successfully with the novel method. The main purpose of this work is to describe and formalize a machine learning -based smoke detection algorithm that can be used by students.

Forest fire smoke detection based on deep learning has been widely studied. Labeling the smoke image is a necessity when building datasets of target detection and semantic segmentation. The uncertainty in labeling the forest fire smoke pixels caused by the non-uniform diffusion of smoke particles will affect the recognition accuracy of the deep learning model. To overcome the labeling ambiguity, the weighted idea was proposed in this paper for the first time. First, the pixel-concentration relationship between the gray value and the concentration of forest fire smoke pixels in the image was established. Second, the loss function of the semantic segmentation method based on concentration weighting was built and improved; thus, the network could pay attention to the smoke pixels differently, an effort to better segment smoke by weighting the loss calculation of smoke pixels. Finally, based on the established forest fire smoke dataset, selection of the optimum weighted factors was made through experiments. mIoU based on the weighted method increased by 1.52% than the unweighted method. The weighted method cannot only be applied to the semantic segmentation and target detection of forest fire smoke, but also has a certain significance to other dispersive target recognition.
