Clarification about Smile/Blink

[kur0saki]

Can you please explain the liveness detection and how can we set it up correctly ?
I run your code , it labels my face as unknown although I encoded it before.
Smiling and blinking doesn't help either.

Any Tips ?

Hello,

The face detection part works. Please check if the steps have been followed correctly.
Also, there is a new PR merged that enhances the liveness detection part. Let us know exactly what steps were followed.

Thank you for replying.
It turns out it was a mistake from my side , my face gets detected correctly , yet "[info] invoking Hodor " doesn't get displayed even with smiling or blinking , which means it doesn't get through the liveliness process.

I read your article on medium , and it was mentioned that you could set up a liveliness pattern for each user , my question is how can I do that ?

Thank you again.

Thanks for using BRAN and also helping us improve it.

To answer your questions:

1. The liveliness detection with pattern detection was an experimental idea that was included to support and validate a generic/common pattern among all users by not being user-specific. This could, however, be extended by storing personalized pattern for each user and using them to validate users

2. Currently, the liveliness detection is limited to smiling and blinking of eyes as opposed to a pattern of blinks/smiles. print('INFO - {}'.format("Invoking Hodor"))gets executed when the user a) smiles and then b) stops smiling after holding the smile for at least a second. The most important point is to ensure that the smile is not a static one.

Alright. Understood.

One more thing , about the liveliness pattern we set up with the argument " -l " at execution.
For example :-l xxxooo

Means what exactly ?
