CountYOLO project checkpoint collection

Public checkpoint storage for https://github.com/Thien-Dan/countyolo (master).

Project-trained CountYOLO density heads

• exnoise: recommended image head based on existing FSC147 evaluations.
• seed3: selected head for the existing video pilot.
• exmix2: comparison head.

These heads need the project architecture and pretrained backbones. Image and video rankings use different configurations.

Upstream checkpoints (unmodified mirrors)

• sam3.pt: Meta SAM 3, originally https://huggingface.co/facebook/sam3 . Copyright Meta. Distributed under the SAM License; see licenses/SAM3-LICENSE.txt. Use and redistribution remain subject to those terms. Acknowledge SAM Materials in research publications.
• countgd_box.pth: official CountGD-Box checkpoint provided by CountVid (https://github.com/niki-amini-naieni/CountVid), original download https://drive.google.com/file/d/1bw-YIS-Il5efGgUqGVisIZ8ekrhhf_FD/view . Copyright Niki Amini-Naieni; see the preserved CountVid and CountGD MIT license notices in licenses/.
• sam2.1_hiera_large.pt: Meta SAM 2.1 large, original https://dl.fbaipublicfiles.com/segment_anything_2/092824/sam2.1_hiera_large.pt . See licenses/SAM2-LICENSE.txt and upstream notices (Apache 2.0).

CountVid is a pipeline using CountGD-Box and SAM 2.1, not a single checkpoint. BERT, YOLO-World and DINOv2 backbones are still obtained using their existing upstream setup. This is a project convenience mirror, not an official Meta or CountVid release. Each upstream file retains its original license; no common license replaces these terms.

See checksums.json for paths, upstream sources, byte sizes and SHA-256 checksums. Download using tools/download_checkpoints.py --group all in the code repo, or choose countyolo, sam3, or countvid.
