react-native face detection using Google MLKit
npm install react-native-face-detectionreact-native face detection using Google ML Kit.
Some part of the code is from react-native-firebase ml-vision package (version 6.4.0) but due to Google separate Firebase ML Kit into Google ML Kit and Firebase Machine Learning then the ml-vision will no longer available on react-native-firebase.
This package bring back face detection feature from ml-vision package.
You can use npm or yarn to install the latest version:
npm
``sh`
npm install --save react-native-face-detection
yarn
`sh`
yarn add react-native-face-detection
Run npx pod-install after installing the package
`js
import FaceDetection, { FaceDetectorContourMode, FaceDetectorLandmarkMode, FaceContourType } from "react-native-face-detection";
async function processFaces(imagePath) {
const options = {
landmarkMode: FaceDetectorLandmarkMode.ALL,
contourMode: FaceDetectorContourMode.ALL
};
const faces = await FaceDetection.processImage(imagePath, options);
faces.forEach(face => {
console.log('Head rotation on X axis: ', face.headEulerAngleX);
console.log('Head rotation on Y axis: ', face.headEulerAngleY);
console.log('Head rotation on Z axis: ', face.headEulerAngleZ);
console.log('Left eye open probability: ', face.leftEyeOpenProbability);
console.log('Right eye open probability: ', face.rightEyeOpenProbability);
console.log('Smiling probability: ', face.smilingProbability);
face.faceContours.forEach(contour => {
if (contour.type === FaceContourType.FACE) {
console.log('Face outline points: ', contour.points);
}
});
face.landmarks.forEach(landmark => {
if (landmark.type === FaceLandmarkType.LEFT_EYE) {
console.log('Left eye outline points: ', landmark.points);
} else if (landmark.type === FaceLandmarkType.RIGHT_EYE) {
console.log('Right eye outline points: ', landmark.points);
}
});
});
}
// Local path to file on the device
const imagePath = '/path/to/face-image.png';
processFaces(imagePath).then(() => console.log('Finished processing file.'));
