+# Camouflaged Person Detector (YOLO, single class)
+
+- Single class: person
+- Phase B fine-tuned model on camo fill/background pairs + negatives
+- Artifacts: `camo-person-yolo.pt` (PyTorch), `camo-person-yolo.onnx` (opset 12, dynamic, simplified), `camo-person-yolo.torchscript`
+
+## Quick usage
+
+### Ultralytics (PyTorch)
+```python
+from ultralytics import YOLO
+model = YOLO("bbopen/camo-person-yolo")  # loads camo-person-yolo.pt by default
+model.predict(source="image.jpg", imgsz=1280, conf=0.25, iou=0.6)
+```
+
+### ONNX Runtime
+```python
+import onnxruntime as ort, numpy as np, cv2
+sess = ort.InferenceSession("camo-person-yolo.onnx", providers=["CUDAExecutionProvider","CPUExecutionProvider"])
+im = cv2.imread("image.jpg"); im = cv2.cvtColor(im, cv2.COLOR_BGR2RGB)
+im = cv2.resize(im, (1280,1280)).astype(np.float32)/255.0
+im = np.transpose(im,(2,0,1))[None]
+outputs = sess.run(None, {"images": im})
+```
+
+## Jetson Orin Nano (export to TensorRT)
+- Install runtime: `python3 -m pip install --upgrade ultralytics`
+- Export FP16 engine:
+```bash
+yolo export model=camo-person-yolo.pt format=engine half=True imgsz=1280 device=0
+```
+- Inference:
+```bash
+yolo task=detect mode=predict model=best_fp16_1280.engine source=path/to/images conf=0.25 iou=0.6 imgsz=1280
+```
+
+## Repro/configs
+- Optional training args: `args.yaml`
+- Optional dataset layout reference: `data.yaml`
+
