| # COCO 2017 LibreYOLO Assets
|
|
|
| This dataset repository hosts small COCO 2017 helper assets used by LibreYOLO dataset YAML files.
|
|
|
| Files:
|
|
|
| - `instances_val2017.json`: official COCO 2017 validation instance annotations.
|
| - `coco2017labels-libreyolo.zip`: YOLO-format train/val label files generated by LibreYOLO from the official COCO 2017 instance annotations.
|
|
|
| No COCO images are included here. LibreYOLO downloads COCO images from the official COCO image hosts.
|
|
|
| ## License and Attribution
|
|
|
| The COCO annotations are licensed by the COCO Consortium under Creative Commons Attribution 4.0. The converted YOLO labels are derived from the official COCO 2017 train/val instance annotations and are provided under the same annotation license.

|
|
| ## Conversion Notes
|
|
|
| The YOLO label zip was generated locally by LibreYOLO from `instances_train2017.json` and `instances_val2017.json`.
|
|
|
| - COCO categories are ordered by official `category_id`, matching LibreYOLO's COCO YAML class order.
|
| - Bounding boxes are converted from COCO `xywh` pixels to normalized YOLO `class x_center y_center width height` rows.
|
| - `iscrowd` annotations are omitted.
|
| - Invalid or empty boxes are omitted.
|
| - One `.txt` label file is written for every train/val image, including empty files for images without valid objects.
