| File | Description |
|---|---|
weights/cardcaptor_v3_best.pt | Full precision PyTorch checkpoint (best epoch) |
onnx/cardcaptor_v3_best.onnx | Optimized ONNX export (80 MB) with built-in NMS |
📚 Dataset
- Name:
merged_dataset_50x3 - Composition: ~60K synthetic renders + ~220 handcrafted captures × deterministic 50× photometric multiplier (~11K effective hand-crafted samples)
- Validation: 55 hand-crafted frames (210 labeled cards) with 90% handcrafted ratio to match real-world deployment
- Label format: YOLO OBB (four polygon corners per box)
🎨 Augmentation Highlights
- Deterministic photometric pre-augmentation for hand-crafted oversampling (brightness/contrast/gamma/noise/blur/HSV shifts)
- YOLO runtime augments: ±60° rotation, ±0.15 translation, ±0.6 scale, ±20° shear, perspective jitter, flipud 0.3, fliplr 0.5
- Composition augments: mosaic (1.0), mixup (0.1), copy-paste (0.15), RandAugment, random erasing (0.4)
🏋️ Training Recipe
- Batch size: 8
- Epochs: 50 (early stop patience 5)
- Optimizer: Ultralytics default (SGD w/ warmup)
- Loss head: OBB-specific DFL + cls losses
- Validation cadence: Every 5 epochs with periodic visualization dumps
- Hardware: NVIDIA RTX 5090, CUDA 12.8

🧪 Inference
from ultralytics import YOLO
model = YOLO("weights/cardcaptor_v3_best.pt")
results = model("card_photo.jpg", conf=0.25)
ONNX (WebGPU / WebAssembly) example:
import onnxruntime as ort
import numpy as np
session = ort.InferenceSession("onnx/cardcaptor_v3_best.onnx", providers=["CPUExecutionProvider"])
input_name = session.get_inputs()[0].name
outputs = session.run(None, {input_name: image_tensor})
✅ Responsible Use
This model only predicts bounding boxes for trading cards. It does not read card text or assess authenticity.
