FaceRecognition-iOS

Overview

This repository demonstrates both face liveness detection and face recognition technology developed from KBY-AI.

In this repository, we integrated KBY-AI's both face liveness detection and face recognition technology into iOS platform.

SDK License

The face recognition project relies on kby-ai's SDK, which requires a license for each bundle ID.

• The code below shows how to use the license:

  FaceRecognition-iOS/FaceRecognition/ViewController.swift

  Lines 37 to 44 in 40b54da

  	var ret = FaceSDK.setActivation("bv5lxJJiUWq/TW3LDv4VUIQLMRN0TeOQSaMmAvt1jIRwfTjMIIh9IZxl5R1wncfiituo8sf9N+62" +
  	"L+CcSdMdDNBaXAdwWNRvahc8G4cUTpH6jcchgqdf0evH/syEqvc4ew8ZXDf/kyMYFMwhXPWsuuDA" +

About SDK

Set up

1. Copy the SDK (facesdk.framework folder) to the root folder of your project.

2. Add SDK framework to the project in xcode

Project Navigator -> General -> Frameworks, Libraries, and Embedded Content

3. Add the bridging header to your project settings

Project Navigator -> Build Settings -> Swift Compiler - General

Initializing an SDK

• Step One

To begin, you need to activate the SDK using the license that you have received.

FaceSDK.setActivation("...") 

If activation is successful, the return value will be SDK_SUCCESS. Otherwise, an error value will be returned.

• Step Two

After activation, call the SDK's initialization function.

FaceSDK.initSDK()

If initialization is successful, the return value will be SDK_SUCCESS. Otherwise, an error value will be returned.

Face Detection and Liveness Detection

The FaceSDK offers a single function for detecting face and liveness detection, which can be used as follows:

let faceBoxes = FaceSDK.faceDetection(image)

FaceRecognition-iOS/FaceRecognition/CameraViewController.swift

Lines 101 to 113 in 40b54da

	CVPixelBufferLockBaseAddress(pixelBuffer, CVPixelBufferLockFlags.readOnly)
	let ciImage = CIImage(cvPixelBuffer: pixelBuffer)
	let context = CIContext()
	let cgImage = context.createCGImage(ciImage, from: ciImage.extent)
	let image = UIImage(cgImage: cgImage!)
	CVPixelBufferUnlockBaseAddress(pixelBuffer, CVPixelBufferLockFlags.readOnly)
	// Rotate and flip the image
	let capturedImage = image.rotate(radians: .pi/2).flipHorizontally()
	let faceBoxes = FaceSDK.faceDetection(capturedImage)
	for faceBox in (faceBoxes as NSArray as! [FaceBox]) {

This function takes a single parameter, which is a UIImage object. The return value of the function is a list of FaceBox objects. Each FaceBox object contains the detected face rectangle, liveness score, and facial angles such as yaw, roll, and pitch.

Create Templates

The FaceSDK provides a function that can generate a template from a UIImage. This template can then be used to verify the identity of the individual captured in the image.

let templates = FaceSDK.templateExtraction(capturedImage, faceBox: faceBox)

FaceRecognition-iOS/FaceRecognition/CameraViewController.swift

Lines 128 to 132 in 40b54da

	let faceBox = faceBoxes[0] as! FaceBox
	if(faceBox.liveness > livenessThreshold) {
	let templates = FaceSDK.templateExtraction(capturedImage, faceBox: faceBox)

The SDK's template extraction function takes two parameters: a UIImage object and an object of FaceBox.

The function returns a Data, which contains the template that can be used for person verification.

Calculation similiarity

The "similarityCalculation" function takes a byte array of two templates as a parameter.

let similarity = FaceSDK.similarityCalculation(templates, templates2: personTemplates)

It returns the similarity value between the two templates, which can be used to determine the degree of similarity between the two individuals.
