About Face Detection Tool
Instantly detect and highlight human faces in your photos using local computer vision processing. This tool quickly scans your image to locate facial features based on skin-tone analysis and geometric patterns, drawing bounding boxes around detected faces without ever uploading your photo to a server.
How to Use This Tool
Upload Portrait
Upload a photo containing one or more faces.
Run Detection
Click "Detect Faces" to scan the image.
Download Result
Save the image with detected faces highlighted.
Frequently Asked Questions
Is this facial recognition?
No, this is face *detection*. It finds *where* a face is, but not *who* it is. It does not store biometric data.
Does it work on black and white photos?
Our current algorithm relies partly on color (skin tone), so B&W performance is limited. We are upgrading to a neural model soon.

Understanding Face Detection Tool
Face detection is the first step in many computer vision applications. This tool uses a "skin-segmentation" algorithm combined with geometric heuristics to identify regions that likely contain human faces, filtering out non-skin background elements.
Why Face Detection Tool Matters
Useful for photographers to check focus on faces, or for developers testing basic computer vision concepts. It can also be used as a privacy check to see which faces are clearly visible in a crowd shot.
Limitations of Face Detection Tool
While this tool is useful, keep in mind:
- Relies on skin-color thresholding (getting better with updates).
- May have false positives in images with skin-colored backgrounds (wood, sand).
- Not robust against faces turned away or covered.
