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://www.markbroyard.com/best-flash-pp-aluminum-lotion-pump-supply-amazing-save/
