Face detector

Face detector is a face detection Android library which can be easily plugged into any camera API (given it provides a way to process its frames).

Face detector is built on top of MLKit's face detection API.

I wrote the following article in order to explain why this project was built, how it's designed and how one can use it in a real-world Android application.

Usage

Only 2 easy steps:

1. Add a FaceBoundsOverlay on top of your camera view.

   
   <FrameLayout
   ...>
   
   // Any other views
   
   <CameraView
       ... />
   
   <husaynhakeem.io.facedetector.FaceBoundsOverlay
       ... />
   
   // Any other views

2. Define a `FaceDetection` instance and connect it to your camera.
```kotlin
val faceDetector = FaceDetector(facesBoundsOverlay)
cameraView.addFrameProcessor {
    faceDetector.process(Frame(
            data = it.data,
            rotation = it.rotation,
            size = Size(it.size.width, it.size.height),
            format = it.format,
            lensFacing = cameraView.facing))
}

Download

1. Add the code below in your root build.gradle at the end of repositories

   allprojects {
   repositories {
       ...
       maven { url 'https://jitpack.io' }
   }
   }

2. Add the dependency

   implementation 'com.github.husaynhakeem:android-face-detector:2.0'
