arcface

Node-ArcFace

Arcsoft Face Cognition Engine.

ArcFace is a Face Cognition Engine, which contains Face Detection, Face Recognition and Face Tracking.

This module is a wrapper of ArcFace C++ SDK used for nodejs.

Installation

with npm

$ npm install arcface --save

with yarn

$ yarn add arcface

Usage

Using Raw SDK

This way you need to know how to use C/C++ pointer, struct and array in nodejs. See ref.

const ArcFace = require('arcface');
 
const TypeDef = ArcFace.TypeDef;
const Lib = ArcFace.Lib;
 
// init FD module
const FD = ArcFace.FD('/path/to/fdsdk.dll');
// init FR module
const FR = ArcFace.FR('/path/to/frsdk.dll');
 
// setting initial variables
const APPID = 'yourAppId';
const FR_SDKKey = 'yourFRSDKKey';
const WORKBUF_SIZE = 40 * 1024 * 1024;
const nScale = 16;
const nMaxFace = 10;
 
// alloc memory
const phEngine = TypeDef.Ref.alloc(TypeDef.MHandle);
const pWorkMem = Lib.malloc(WORKBUF_SIZE);
 
// initial FR Engine
const nRet = FR.AFR_FSDK_InitialEngine(
    APPID, 
    FR_SDKKey, 
    pWorkMem, 
    WORKBUF_SIZE, 
    phEngine
);
 
// other usages are same as the official sample code
// ...
 
 

Using Wrapped SDK

const ArcFace = require('arcface');
 
const arcface = new ArcFace();
 
// init FD Engine
arcface.initialFDEngine('/path/to/fd.dll', {
    appId: 'yourAppId',
    sdkKey: 'yourFDKey'
});
// init FR Engine
arcface.initialFREngine('/path/to/fr.dll', {
    appId: 'yourAppId',
    sdkKey: 'yourFRKey'
});
 
// parse image file to ASVLOFFSCREEN
const asvl = await arcface.parseImage('/path/to/image.jpg');
 
// face detection
const faces = arcface.detect(asvl);
 
// extract face featrue
const faceModel = arcface.extractFeature(asvl, faces.rcFace[0], faces.lfaceOrient[0]);
 
// ...
