```

{% endcode %}

* Build Project.

### - Integration Guide

* Import FaceSDK

```kotlin
import com.bio.facesdk.FaceBox
import com.bio.facesdk.FaceDetectionParam
import com.bio.facesdk.FaceSDK
```

* Activate and Initialize FaceSDK

```kotlin
var ret = FaceSDK.setActivation(license_str)

if (ret == FaceSDK.SDK_SUCCESS) {
    ret = FaceSDK.init(assets)
}
```

* YUV to Bitmap for camera frame

```kotlin
override fun process(frame: Frame) {
    val bitmap = FaceSDK.yuv2Bitmap(frame.image, frame.size.width, frame.size.height, cameraOrientation)
    ...
```

* Set `FaceDetectionParam` and Detect Face

```kotlin
val faceDetectionParam = FaceDetectionParam()
faceDetectionParam.check_liveness = true
faceDetectionParam.check_liveness_level = SettingsActivity.getLivenessModelType(this)
faceDetectionParam.check_eye_closeness = true // available for pro version
faceDetectionParam.check_face_occlusion = true // available for pro version
faceDetectionParam.check_mouth_opened = true // available for pro version
faceDetectionParam.estimate_age_gender = true // available for pro version
var faceBoxes: List<FaceBox>? = FaceSDK.faceDetection(bitmap, faceDetectionParam)
```

* Extract Face Template

```kotlin
val faceBox = faceBoxes[0]
val templates = FaceSDK.templateExtraction(bitmap, faceBox)
```

* Calculate Similarity

```kotlin
val similarity = FaceSDK.similarityCalculation(templates, person.templates)
```
