💾 Checkpoints

To keep this repository lightweight, all model checkpoints are hosted on Hugging Face.

Please download the required weights and place them in your local model_zoo/ directory.

File	Purpose	Download
`gps_plus_final.pth`	Frozen GPS-Gaussian+ backbone checkpoint	Download
`ibrsteg_test_weight.pth`	Inference-only IBRSteG/GAS checkpoint for testing	Download

Quick Download via CLI:

mkdir -p model_zoo
wget [https://huggingface.co/lingxiang2023/IBRSteG/resolve/main/model_zoo/gps_plus_final.pth](https://huggingface.co/lingxiang2023/IBRSteG/resolve/main/model_zoo/gps_plus_final.pth) -O model_zoo/gps_plus_final.pth
wget [https://huggingface.co/lingxiang2023/IBRSteG/resolve/main/model_zoo/ibrsteg_test_weight.pth](https://huggingface.co/lingxiang2023/IBRSteG/resolve/main/model_zoo/ibrsteg_test_weight.pth) -O model_zoo/ibrsteg_test_weight.pth

Note: The original full checkpoint (~489 MB, containing optimizer/scheduler states) has been trimmed to the inference-only ibrsteg_test_weight.pth (~163 MB, containing explicitly formulated camera parameter steganographic keys and minimal metadata) for faster evaluation.
