# LibreDFINEx-seg

D-FINE-seg X-Large COCO instance segmentation weights repackaged for LibreYOLO.

## Source

Derived from [ArgoHA/D-FINE-seg](https://github.com/ArgoHA/D-FINE-seg) (v0.1.0),
upstream checkpoint `dfine_seg_x_coco.pt` downloaded from
[ArgoSA/D-FINE-seg](https://huggingface.co/ArgoSA/D-FINE-seg).
Copyright (c) 2026 The D-FINE-seg Authors. Licensed under the
Apache License, Version 2.0.

D-FINE-seg extends [D-FINE](https://github.com/Peterande/D-FINE)
(Copyright (c) 2024 The D-FINE Authors, Apache-2.0) with a lightweight
instance-segmentation mask head.

## Modifications

Wrapped the upstream state dict in LibreYOLO checkpoint metadata:
`model_family="dfine"`, `size="x"`, `task="segment"`, `nc=80`,
and `imgsz=640`. Learned parameters are unchanged.
See `weights/convert_dfine_weights.py` in the
[LibreYOLO source repository](https://github.com/LibreYOLO/libreyolo).
