IRForge artifacts

Data, checkpoints, predictions, and detection artifacts of IRForge, which adapts image-conditioned foundation flow models (FLUX.2-klein-base-4B, Qwen-Image-2.1) to RGB-to-infrared translation and uses them as data engines for infrared small target detection. The code and the reproduction guide (docs/reproduce.md) are in the IRForge repository.

The layout mirrors the code's IRFORGE_WORK directory. MANIFEST.json lists every file with its size; each *.tar unpacks into the directory given by its unpack_to entry. experiments/tools/fetch_release.py PART ... downloads parts and unpacks them (raw, paper, checkpoints, predictions, detection, backgrounds).

Path Content
data/raw/20260922pbw/*.tar paired RGB-infrared images with train.txt / test.txt: FLIR-aligned (LWIR) and VEDAI (NIR), full sets and the 1,000-pair Selected subsets
runs/RUN/saves/RUN/checkpoints/checkpoint-N/ PEFT LoRA adapters (Flow-Factory checkpoints): Stage 1 translators, reward-tuned continuations (checkpoint-0 is the starting point), DMD2 / TDM students
eval/RUN/SETTING/SPLIT/ metrics.json, sampling.json (and merge.json for interpolated translators), predictions.tar with the translated test images
irstd/datasets.tar synthesized SIRST detection datasets in the BasicIRSTD layout, including the SIRST320 split
irstd/runs/DATASET/MODEL_seedS/ detector scores (test_scores.json, val_scores.json) of every detection run
irstd/backgrounds/*.tar translated Places365 background pools, 4,200 scenes each
irstd/*.json, irstd/*.npz, runs/*/train.log background analysis, DINOv2 domain probes, and RL training logs read by the paper tables
release/inputs_make_*.txt every file the paper's table and figure scripts read
