A React Native module for UVC camera access with face detection capabilities.

## Installation

```sh
npm install react-native-uvc-camera
# or
yarn add react-native-uvc-camera
```

## Usage

```javascript
import { UVCCamera, FaceDetector } from 'react-native-uvc-camera';

// Using the camera component
const App = () => {
  const handleFacesDetected = ({ faces }) => {
    console.log('Detected faces:', faces);
  };

  return (
    <UVCCamera
      style={{ flex: 1 }}
      onFacesDetected={handleFacesDetected}
      faceDetectionMode={FaceDetector.Constants.Mode.FAST}
    />
  );
};

// Using the face detector
const detectFaces = async (imageUri) => {
  const faces = await FaceDetector.detectFacesAsync(imageUri, {
    mode: FaceDetector.Constants.Mode.ACCURATE,
    detectLandmarks: FaceDetector.Constants.Landmarks.ALL,
    runClassifications: FaceDetector.Constants.Classifications.ALL,
  });
  
  console.log('Detected faces:', faces);
};
```
