A high-accuracy real-time smoke segmentation algorithm was proposed,aiming at the lack of a real-time smoke segmentation algorithm applied to the actual monitoring systems in the field of smoke segmentation.A lightweight multi-resolution convolution module to extract feature maps in parallel was used in the algorithm,which met the needs of real-time segmentation while obtaining rich semantic information.A smoke foreground enhancement module was proposed to enable smoke pixels to be merged with their corresponding foreground enhancement representations,while avoiding the interference of background information,thereby improving the accuracy of segmentation.A residual attention module was proposed to enhance important feature information from the two dimensions of channel and space,and suppress invalid information.The algorithm had a mean intersection over union of 91.27%on the self-built data set,the prediction time of each picture was 39.06 ms,and the network weight was 74.66 MB.Comparison results on the public data set show that the comprehensive detection performance of this algorithm is better than that of other smoke detection algorithms.The algorithm has high segmentation accuracy,fast detection speed and the model is lightweight,which can be applied to actual video surveillance systems.
