The existing algorithm for detecting the helmet wear by coal miners has the problem of difficulty in achieving a good balance between detection accuracy and speed. In order to solve the above problem. based on the YOLOv4 model. a lightweight model (M-YOLO) that integrates coordinate attention and multi-scale is proposed and applied in safety helmet wearing detection. https://ashleyshomestores.shop/product-category/outdoor-left-and-right-arm-loveseat-with-cushion/
