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.

glidefacedetectiontransformation's Issues

Does FaceCenterCrop support for circle Image？

Possible to get the rect coords of the detected face?

Image gets pixelated

Hello Rohit,

Thanks for this amazing library. Great work. I'm using your library to show image thumbnails in a recycler view. The images appear to be pixelated. Viewing the image thumbnail without adding this library does not pixelate the image.

Thanks!!

Library dependencies

What is the use of play-services? Because it will increase the apk size.

Throws RuntimeExeption: Initialize GlideFaceDetector

I have GlideFaceDetector.initialize(context) in the onCreate(). when opening an activity and coming back to the one using GlideFaceDetecor inside a RecyclerView, when scrolled, results in a crash with the above message.

Please update version and publish for gradle dependency

the version 0.3 doesn't work with any recent version of glide, it crashes; It appears to have been updated recently but not published

FaceAware Imageview

I am looking for face Aware Image-view. Instead of cropping Image or simply center crop scale type of Imageview, the face should detect in image-view and adjust face to center of Image-view.
As your library crop the picture i want to do it without cropping picture.

I got Library in IOS but not getting anything in Android.

The second scenario what does this library do if image have 3 faces?
Can anyone help me out? Thank You.

Is there any way to cache Face transformation data

I have to apply face detection on hundreds of images. This increases the time it takes to load these images. Is there any way I can cache the data of these images so that while scrolling or when loading the same images again it will load them instantly. Any kind of help will be appreciated. Thankyou for making such an amazing library.
