RF-DETR Nano Finetuned on GC10-DET

Fine-tuned RF-DETR Nano object detector on the GC10-DET benchmark dataset, trained and evaluated as part of DetectionBench -- a framework for reproducibly benchmarking modern object detectors with identical training recipes and evaluation metrics across multiple real-world datasets.

Usage

Install Dependencies

pip install rfdetr huggingface_hub

Load Model from Hugging Face

from huggingface_hub import hf_hub_download
import rfdetr

weights = hf_hub_download(
    repo_id="dronefreak/gc10det-rfdetr-nano",
    filename="checkpoint_best_total.pth"
)

model = rfdetr.RFDETRNano(pretrain_weights=weights)

Run Inference

detections = model.predict("image.jpg", threshold=0.25)

Performance

Evaluated on the GC10-DET test split, using DetectionBench's standard evaluation pipeline (detectionbench-evaluate).

GC10-DET Model Zoo

Every model DetectionBench has trained and evaluated on GC10-DET so far, for full transparency -- see DetectionBench for the smaller, curated comparison set used on the project README.

Per-Class Performance

This model was evaluated with Supervision's detection metrics, which report mAP/Precision/Recall directly but don't produce a confusion-matrix plot the way Ultralytics' validator does.

Training Framework

This model was trained using DetectionBench, an open-source framework for benchmarking object detectors across multiple real-world datasets with a common pipeline.

Features include:

• A dataset-adapter registry for converting real-world datasets into a canonical format
• Identical training/evaluation recipes across model families (Ultralytics YOLO/RT-DETR, RF-DETR)
• Hardware profiling (latency, FPS, VRAM, parameters, FLOPs)
• One-command reproducibility via versioned Hydra configs

Known Limitations

• No official split: GC10-DET's paper defines no train/valid/test division, so this adapter creates a deterministic seeded 80/10/10 split over the sorted-then-shuffled image list -- results are not directly comparable to a paper that uses a different split.
• Small dataset: only 1,840 training images (2,300 total) across 10 classes, so absolute scores are more sensitive to the specific split than on the project's larger datasets, and per-class scores on the rarest classes are noisy.
• Severe class imbalance: silk_spot is 24.8% of all boxes, while crease has only 74 instances (2.1%) across the whole dataset -- its per-class score is measured on very few examples and should be read with caution.
• Sparse, mostly single-defect images: 1.55 instances/image on average (median 1, max 11), unlike the crowded-scene datasets (PKLot/VisDrone/UAVDT) -- this is a localization task on large, easy-to-see boxes (median 3.48% of image area) rather than a small-object or dense-detection problem.
• Different visual domain: GC10-DET is grayscale industrial line-scan imagery of rolled steel surfaces, not a natural-scene photo -- the first industrial-inspection dataset in DetectionBench, so these results say nothing about how these checkpoints would perform on outdoor/natural-scene detection or vice versa.
