Face Detection in Preview Camera Feed on Flutter-CodePudding

The

CodePudding user response：

Firstly, get the image data. This can be done by either using the camera plugin's output, or even directly communicate with the SurfaceView/TextureView.

Secondly, run face detection algorithm. If you do not need cross-platform, https://medium.flutterdevs.com/face-detection-in-flutter-2af14455b90d?gi=f5ead7c6d7c9 MLKit sounds good. If needing cross-platform, you can use Rust algorithms like https://github.com/atomashpolskiy/rustface and bind Rust code to Flutter via https://github.com/fzyzcjy/flutter_rust_bridge. Or, use C face detection algorithms and bind to Flutter (though setup may be a bit harder).

Lastly, once you know the face, draw a box around it. For example, Container widget.

CodePudding user response：

You can use Face Detection of Google ML Kit. You can detect the faces offline using this.

You can see example app.
