I need to implement facial recognition authentication in my Android application, where the user currently enters the user name and password, he will register his image and, to access, I need to activate the camera of the device and validate the face with a previously saved image .
I've done a lot of research on the internet, and would like to confirm some of the information I've read.
Android does not have native facial recognition, FaceDetection only reads the image and detects the face but does not recognize it. The implementation of this facial recognition should be according to the processor, being ARM, Snapdragon, etc. Snapdragon provides the SDK for implementation, since ARM has to copy the bibliotecas.so to implementation and use the Java OpenCV, which I tested in my S3 and stopped the processor of the device, restarting the same several consecutive times. >
Is there really no API to simply read the image, compare and return it if it is identical to the one captured by the camera or not?
