capawesome-face-detection works with images. iI requested for realtime camera face detectio.

@Saqib92 we just closed 2 PR because it look unfnished fr us but maybe you wanna test it locally and see if that help you ?

Love this use case (Snap-style overlays are always fun) 😄

To move this from idea → implementable, could you share target requirements:

1. minimum FPS needed for detection
2. landmarks needed (face box only vs eyes/nose/mouth/contours)
3. Android/iOS parity requirements
4. whether tracking multiple faces is required

Reason: real-time detection usually needs a dedicated native pipeline (camera frames + ML loop), which is a bit different from still-image ML APIs.

If helpful, we can frame this as a separate plugin/module focused on realtime face tracking so Camera Preview stays lean.

Label suggestion for maintainers: enhancement, needs-spec.

Do as you please.

/attempt #200

I can implement face detection + face-position output cross-platform (iOS Vision + Android ML Kit), with normalized bounding boxes and docs. If approved, I will start now.
