How to use it?

STEP 1:

Grab via Gradle

repositories {
    jcenter()
}
dependencies {
    compile 'com.github.aryarohit07:glide-facedetection-transformation:0.3.0'
}

Or via Maven

<dependency>
  <groupId>com.github.aryarohit07</groupId>
  <artifactId>glide-facedetection-transformation</artifactId>
  <version>0.3.0</version>
</dependency>

STEP 2:

Initialize the detector (May be in onCreate() method)

GlideFaceDetector.initialize(context);

STEP 3:

Set glide transform

Glide.with(yourFragment)
    .load(yourUrl)
    .transform(new FaceCenterCrop())
    .into(yourView);

STEP 4:

The face detector uses native resources in order to do detection. For this reason, it is necessary to release the detector instance once it is no longer needed (May be in onDestory() method)

GlideFaceDetector.releaseDetector();

Note: If no face is detected, it will fallback to CENTER CROP.

Library dependencies:

com.google.android.gms:play-services-vision:9.4.0
com.github.bumptech.glide:glide:3.7.0

TODO

• Making it generic for any point.

Performance: Time taken to detect faces in the original image.
