## Common Use Cases

## Configuration Files

Configuration files use YAML format. Place one of these files in your working directory:

- `app.yaml`
- `config/app.yaml`

Example configuration:

```yaml
defaults:
  setting_threshold: 0.1
  max_keypoints: 2000
  enable_ransac: true
  ransac_method: CV2_USAC_MAGSAC
  setting_geometry: Homography
```
