Abstract

Cigarettes, as critical indicators of smoking behavior, often appear as small targets in video surveillance. Due to camera resolution limits and shooting distance, cigarettes may only appear as bars, increasing false detection possibilities. Additionally, complex environments or lighting can cause partial or complete occlusion of cigarette targets, complicating detection. To accurately and quickly identify smoking behavior in such conditions, an improved YOLOV8-based method is proposed to enhance real-time recognition performance. The improved YOLOV8 backbone network uses deformable convolution layers to replace some conventional layers, extracting the smoking behavior feature map. Deformable pooling layers are added to process and extract critical features. In the enhanced neck network, a residual attention module combines channel and spatial attention mechanisms to refine the critical feature map. The detection head network employs scale, spatial, and task awareness attention modules to fuse important features from different scales, locations, and tasks, respectively. This fusion determines the smoking behavior recognition frame and score, optimizing the recognition process. An improved loss function further refines the recognition box, boosting accuracy. Experiments demonstrate that this method effectively extracts critical features of smoking behavior, achieving better feature extraction and accurate identification across varying lighting conditions, resulting in high accuracy.
