Face Detection Y Euler face orientation is inverse

[FranPR9]

Step 2: Describe your environment

• Android device: Samsung galaxy A3___

• Android OS version: 5.1.1_

• Google Play Services version: 14.7.99_

• Firebase/Play Services SDK version: _____
  api 'com.google.firebase:firebase-invites:16.0.4'
  api 'com.google.firebase:firebase-messaging:17.3.4'
  api 'com.google.firebase:firebase-core:16.0.4'
  api 'com.google.android.gms:play-services-location:16.0.0'
  api 'com.google.android.gms:play-services-analytics:16.0.4'

  implementation 'com.google.firebase:firebase-ml-vision:18.0.1'
  implementation 'com.google.firebase:firebase-ml-vision-face-model:17.0.2'
  implementation 'com.google.firebase:firebase-ml-vision-image-label-model:17.0.2'

Step 3: Describe the problem:

In most of the devices that I have used, when you turn your head left the Y euler angle is positive and when turning right the angle is negative.
But in a Samsung Galaxy A3 Android 5.1.1 this is inverse, left negative and right positive.
Is there a way to know if the angles are inversed in an specific device?

Steps to reproduce:

1. add the mlkit face recognition accurate mode code
2. __ run the app and check te Euler y angle__
   3.- turn your head left and right

Observed Results:

Y Euler angle:
left negative and right positive.

Expected Results:

Y Euler angle:
left positive and right negative.

Hi @FranPR9
Looks like this is a known issue on Samsung and Oneplus devices.
Can you take a look at the following commend and let me know if the solution proposed there works for you?

Hi! thanks for the help, but I don't think It has so much to do with the image rotation.
i get the rotation from the device like this :
getActivity().getWindowManager().getDefaultDisplay().getRotation();
and it has the same(0) as other devices that have a "normal" Y euler face orientation angle.

Is this issue solved or there is some workaround for this? It is now 2020 and I am facing the same issue with Samsung Galaxy Note 8. The angles are inversed in the accurate mode.

For ML Kit, we process the face detection with the incoming image. If the Y euler number is different, I suspect the image we received in ML Kit is flipped. Sorry, I do not have Samsung device at hand. Could you verify the image you send to ML Kit is different in Samsung Galaxy Note 8 device, comparing to other device?

I am using the same code as that of the Google sample. And apart from Note 8 I have checked with several other devices. And the response is same regarding the eular angle.

Hi, sorry for the late reply. Have you tried CameraX? It helps to deal with many camera issues caused by device differences.
