🔍 YOLOv11l — UI Groups Detection

This model is a fine-tuned version of Ultralytics/YOLO11, trained to detect UI groups (e.g., toolbars, tab groups) in macOS application screenshots.

It is part of the Screen2AX project, a research-driven effort to generate accessibility metadata for macOS applications using vision-based techniques.

⚠️ AGPL-3.0 licence — read before integrating. This model inherits the AGPL-3.0 licence from Ultralytics YOLO11. Embedding it in a product or service — including serving it behind a network API — requires open-sourcing the integrating application under AGPL-3.0, or obtaining a commercial Ultralytics Enterprise Licence. Details in License.

🧠 Task Overview

Task: Object Detection
Target: macOS UI groups
Supported Label(s):
```
['AXGroup']
```

This model detects higher-level UI groupings that are commonly used to structure accessible interfaces (e.g., AXGroup, AXTabGroup, AXToolbar, etc.).

🗂 Dataset

Training data: macpaw-research/Screen2AX-Group

🚀 How to Use

🔧 Install Dependencies

pip install huggingface_hub ultralytics

🧪 Load the Model and Run Predictions

from huggingface_hub import hf_hub_download
from ultralytics import YOLO

# Download the model from the Hugging Face Hub
model_path = hf_hub_download(
    repo_id="macpaw-research/yolov11l-ui-groups-detection",
    filename="ui-groups-detection.pt"
)

# Load and run prediction
model = YOLO(model_path)
results = model.predict("/path/to/your/image")

# Visualize or process results
results[0].show()

📜 License

This model is licensed under the GNU Affero General Public License v3.0 (AGPL-3.0), inherited from the original YOLOv11 base model and the Ultralytics training framework.

What this means in practice:

✅ Research, evaluation, and open-source (AGPL) projects — free to use, modify, and redistribute, provided derivative works are also released under AGPL-3.0.
⚠️ Commercial or closed-source use — AGPL-3.0 is a strong copyleft licence whose obligations also trigger on network use: shipping this model inside a proprietary application, or exposing it through a hosted API, requires releasing the integrating application's source code under AGPL-3.0.
💼 Need a proprietary integration? Ultralytics offers a commercial Enterprise Licence that lifts the AGPL obligations for YOLO models and their derivatives, including fine-tunes such as this one.
