Starts the user-facing camera automatically.
Uses the source camera ratio in landscape and a centre-cropped 1:1 preview in portrait.
Guides the user with a circular capture area and a moving confidence box.
Requires one face, confidence ≥ 0.90, face size ≥ 12%, and horizontal centering.
Requires the accepted face position and size to remain stable for about two seconds.
Locks the stable face image and stops inference while keeping the camera preview visible.
Restarts detection automatically after ten seconds, or immediately when Detect again is selected.
Displays the locked face in the lower-right corner and keeps Detection Result and Activity in two equal cards.

Development with the sibling SDK

cd ../sdk
npm install
npm run build

cd ../demo-ai-face-detector
npm install
npm run dev

Both dev and the CUTOS build copy version-matched model assets through the SDK's asset command.

Build and package

npx cutos lwa build

The generated package is:

release/demo-ai-face-detector-v<version>.lwa

The LWA version comes from public/config.json; package.json intentionally remains 0.0.0.

Upload and publish

npx cutos login --username office
npx cutos lwa upload
npx cutos lwa list demo-ai-face-detector
npx cutos lwa publish --lwa <content-id> --device <device-id>

For a release build, depend on the published npm SDK rather than file:../sdk.
