Yolov11x Codh Char

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model was trained on the CODH Kuzushiji Character Shape Dataset, which contains character images from various Japanese historical documents.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
