short_description: Smple Face Shape Detection using Mediapipe and ML
---
## AI Face Shape Detector (Hugging Face Space)
Upload a front-facing photo (or use your webcam) and this Space predicts your **face shape** and shows a **MediaPipe face-mesh overlay** plus **confidence scores**.
Full app available at [attractivenesstest.com/face_shape](https://attractivenesstest.com/face_shape).
### Supported face shapes
- **Oval**
- **Round**
- **Square**
- **Heart**
- **Oblong**
### How it works (from `app.py`)
- **Face landmark extraction**: Uses **MediaPipe Face Mesh** (up to **478 landmarks**) to detect a single face.
- **Landmark normalization**: Centers landmarks using the eye/iris center, applies roll correction, and scales by inter-eye distance.
- **Classification**: Flattens normalized landmark coordinates and runs a **pickled scikit-learn classifier** (loaded from `face_shape_model.pkl`) with a label encoder (`label_encoder_rf.pkl`).
- **Outputs**:
- An image with a face mesh/contour overlay
- A formatted result card (shape + description + styling tip)
- Per-class confidence scores
### Tips for best results
- Use a **front-facing** photo with good lighting
- Ensure your **entire face** is visible
- Remove glasses if possible
- Avoid tilting your head
### Run locally
```bash
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
python app.py
```
Then open the Gradio URL printed in your terminal.
### Notes / limitations
- This demo expects **one clear, visible face** in the image (`max_num_faces=1`).
- If no face is detected, the app will return an error message asking for a clearer photo.
- Uploaded images are processed in-memory by the app; the code does not intentionally save uploads to disk.
