Detection Targets
SmartBlur can detect and blur different types of subjects:
| Target | Description | Default |
|---|---|---|
| Faces | Detect human faces (front and profile) | On |
| Full Body | Detect entire human body | Off |
| Upper Body | Detect head and torso | Off |
| License Plates | Detect and blur vehicle plates | Off |
Enable or disable targets from the Detection panel in the main window.
Sensitivity Settings
Adjust how aggressive the AI is at finding targets:
| Level | Behavior |
|---|---|
| Low | Only high-confidence detections. May miss some faces. |
| Medium (default) | Good balance. Catches most faces with few false positives. |
| High | Maximum detection. May occasionally detect false positives. |
360-Degree Detection
By default, SmartBlur detects faces in the primary direction (front-facing). Enable 360-degree mode to also detect:
- Profile faces (side views)
- Partially occluded faces
- Faces at extreme angles
Note: 360-degree mode increases processing time and may produce more false positives.
Face Padding
Face padding adds extra margin around each detected face before applying blur:
- 0% — Blur only the exact detection box.
- 10% (default) — Adds comfortable margin around the face.
- 50% — Large margin, covers head and some shoulders.
Increase padding to ensure complete coverage, especially for profile faces or when the detection box is slightly off.
Minimum Face Size
Controls the smallest face size the AI will detect:
- Small (default) — Detects faces as small as 20x20 pixels. Good for crowd photos.
- Medium — Ignores very small faces. Faster processing.
- Large — Only detects prominent, close-up faces.
Body Detection
When body detection is enabled:
- Full Body blurs from head to toe.
- Upper Body blurs from head to waist.
- Body detection uses more processing power than face-only detection.
Performance Impact
| Setting | Speed Impact | Accuracy Impact |
|---|---|---|
| High sensitivity | Slower | More detections |
| 360-degree mode | Slower | More detections |
| Body detection | Much slower | N/A |
| Small min face size | Slower | More small faces found |
Tips
- Start with default settings and adjust if faces are being missed or falsely detected.
- For crowd photos, use High sensitivity with Small min face size.
- For video calls, Medium sensitivity is usually sufficient.
- Face padding of 10-30% works well for most scenarios.
