Source description
YOLOv11x CODH Character
Model Description
This is a YOLOv11x model fine-tuned for detecting and recognizing characters in Japanese historical documents (古典籍/Koten-seki). The model is trained on the 日本古典籍くずし字データセット (CODH Kuzushiji Dataset).
Intended Uses
- Character detection in historical Japanese manuscripts
- Kuzushiji (くずし字) character localization
- Pre-processing for OCR pipelines on classical Japanese texts
How to Use
from ultralytics import YOLO
# Load model
model = YOLO("nakamura196/yolov11x-codh-char")
# Run inference
results = model.predict("your_image.jpg", conf=0.25, iou=0.45)
# Process results
for result in results:
boxes = result.boxes
print(boxes)
Or download the model file directly:
from huggingface_hub import hf_hub_download
model_path = hf_hub_download(repo_id="nakamura196/yolov11x-codh-char", filename="best.pt")
Training Data
The model was trained on the CODH Kuzushiji Character Shape Dataset, which contains character images from various Japanese historical documents.
Model Architecture
- Base Model: YOLOv11x (extra-large variant)
- Task: Object Detection
- Framework: Ultralytics
Limitations
- Optimized for historical Japanese documents; may not perform well on modern printed text
- Performance may vary depending on the document quality and writing style
