Hybrid connected attentional lightweight network for gangue intelligent segmentation in top-coal caving face

Journal of Intelligent & Fuzzy Systems, 2023
The estimation of gangue content is the main basis for intelligent top coal caving mining by computer vision, and the automatic segmentation of gangue is crucial to computer vision analysis. However, it is still a great challenge due to the degradation of images and the limitation of computing resources.
