This demo showcases a 3D passive liveness detection technique for detecting spoofed faces.
In real-time, a single image captured from the Android camera computes a liveness score.

This project uses kby-ai's liveness detection SDK. The SDK requires a license per application ID.

Copy the SDK (libfacesdk folder) to the root folder of your project.
-
Add SDK to the project in settings.gradle
include ':libfacesdk'
- Add dependency to your build.gradle
implementation project(path: ':libfacesdk')
- 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.init(getAssets());
If initialization is successful, the return value will be SDK_SUCCESS. Otherwise, an error value will be returned.
The FaceSDK offers a single function for detecting face and liveness detection, which can be used as follows:
FaceSDK.faceDetection(bitmap)
This function takes a single parameter, which is a bitmap 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.
The SDK provides a function called yuv2Bitmap, which converts a yuv frame to a bitmap. Since camera frames are typically in yuv format, this function is necessary to convert them to bitmaps. The usage of this function is as follows:
Bitmap bitmap = FaceSDK.yuv2Bitmap(nv21, image.getWidth(), image.getHeight(), 7);
The first parameter is an nv21 byte array containing the yuv data.
The second parameter is the width of the yuv frame, and the third parameter is its height.
The fourth parameter is the conversion mode, which is determined by the camera orientation.
To determine the appropriate conversion mode, the following method can be used:
1 2 3 4 5 6 7 8
