Face matches

[stefi92]

Hello, is it possbile to recognize face from camera and pair it with user in database? Next time when camera takes my photo, i want to compare if it matches with the saved one.

It's possbile, but you need a pro in face recognize to do that or you can use library OpenCV or Face API of microsoft.

May be requestPermissions in some devices have bugs. You can fix by down targetSdkVersion in grandle to below 23 (may be 22 or 21)

defaultConfig {
applicationId "m.tri.facedetectcamera"
minSdkVersion 11
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
