Question

hi, I've trained detection model with my custom polygon annotated dataset. 'val_batch0_labels.jpg' showed me bboxes not polygons. I am curious how yolov5 have transformed my polygons into bboxes. I'll really appreciate it if you can point out where is that code line. thanks.

@6894556 hello! Thanks for reaching out. YOLOv5 converts polygons to bounding boxes by finding the minimum and maximum x and y coordinates of the polygon points. This process effectively creates a bounding box that encompasses the entire polygon. The conversion code is part of the dataset loading utilities.

For the exact implementation, you can refer to the dataset loading code in the YOLOv5 repository. If you need more detailed guidance, please check out our documentation at https://docs.ultralytics.com/yolov5/ for further information on how datasets are handled.

If you have any more questions or need further assistance, feel free to ask. Happy coding! 😊👍
