Face Recognition React Native SDK

Face recognition React Native SDK with liveness detection

Code

How to Run

1. Set Up React-Native Development Environment

You can refer to React Native official document to setup enviroment.

2. How to run Android App

yarn
cd example
yarn android

3. How to run the iOS App

yarn
cd example
yarn
cd ios
pod install

And then, open the FaceRecognitionReactNative.xcworkspace in Xcode and run.

4. Install license

This code shows how to use the license

const initSDKAsync = async () => {
      try {
        if (Platform.OS == 'ios') {
          var ret = await FaceSDKModule.setActivation(
            'ZxU5Xu7XDitkVZ2y6ooEnkM2aianIE0MC8DncGam0djE+QHVQuNClk+9yJkEElg3zj6KSmloIUbcIYzayCmjdqT/qLCpNg4IHx4CuMOSHuafQLDFFSh/C3pU8sfAHn5f57dXKRPS73tSN52hTlQOZtl99J+47U8oShMmcruG6IdWKj//8ZQm3KkiOAxMZ7IOeoj3lRBnWPr4aZeLDTll9jtNqhIW5S1ElUI8R7ViJiJiHgw0FHwqkQAXXcoUly84HuDr4/W7OGNi7yBfOug21TNgCkHc5yaaerRzqEsAFq61YHlAFNmGhNFhscGEqPfROwcU1BLb1HwbrJQCsZJDjQ=='
          );
          console.log('set activation:', ret);
        } else {
          var ret = await FaceSDKModule.setActivation(
            'EGH+RzwjnvhbtLxq49y1nDDSxguXUZPkgifx/9EGeg3qGrrnsZbP4/nQH1hE/BQyt86UqMByIaUuoqUvJORHPnJBOFSkEIEL4GX1FQjMzDZabA/V2HmkEaY9hAXlIkd4aDAdy7YI37hqfGgvsg8OgSi12aM7ScyHwzC/mbFkTSMHMM/+nB9aWBaO79nCSRWQfpOoQjh823fCwVIJc7YPLxJJjlPZaTASx1DPnoZ8qaCl7tVJpmGIwgTlJq/0ywLrok+q6usCkERqVGloab3O4YcfpZ1Pw7kvUjBvGsR5eWaMzS+xx1tlLvcv0F0pRhJeBRln+2Th57AeNMxXFLxfyQ=='
          );
          console.log('set activation:', ret);
        }

API Usage

1. FaceSDKModule

Activate the FaceSDKModule

Call the setActivation method:

var ret = await FaceSDKModule.setActivation("...");
console.log("set activation:", ret);

Initialize the FaceSDKModule

Call the initSDK method:

var ret = await FaceSDKModule.initSDK();

Set Parameters

Use the setParam method to configure settings:

var ret = await FaceSDKModule.setParam(checkLivenessLevel);

Extract Faces

Use the extractFaces method to detect and extract faces from an image:

var faceBoxes = await FaceSDKModule.extractFaces(uri);

Calculate Face Similarity

Compare two face templates using the similarityCalculation method:

const similarity = await FaceSDKModule.similarityCalculation(
    face.templates,
    person.templates
);

2. Working with camera stream

Build the Camera Screen & Process Face Detection

To implement the native camera and process face detection, refer to the example/src/FaceRecognitionPage.tsx file in the repository.

<FaceRecognitionSdkView style={styles.box} livenessLevel={1} cameraLens={1} />

Get Face Detection Results

Use the following code to listen for face detection events:

const eventEmitter = new NativeEventEmitter(FaceSDKModule);
let eventListener = eventEmitter.addListener('onFaceDetected', (event) => {
    setFaces(event);
    if (recognized == false) {
        identifyPerson(event);
    }
});

Start & Stop the Camera

Start Camera

const startCamera = async () => {
    await FaceSDKModule.startCamera();
}

Stop Camera

const stopCamera = async () => {
    await FaceSDKModule.stopCamera();
}
