Face Features Recognition
Subject to your needs, you can enable automatic recognition of such face features as gender, age, emotions, glasses, and/or beard. This functionality can be activated on both GPU- and CPU-accelerated video face detectors.
To enable automatic recognition of face features, open the /etc/findface-extraction-api configuration file and enable relevant recognition models: gender, age, emotions, glasses3, and/or beard. Be sure to choose the right acceleration type for each model, matching the acceleration type of findface-extraction-api: CPU or GPU. Be aware that findface-extraction-api on CPU can work only with CPU-models, while findface-extraction-api on GPU supports both CPU- and GPU-models.
sudo vi /etc/findface-extraction-api.ini
models:
age: faceattr/age.v1.cpu.fnk
emotions: faceattr/emotions.v1.cpu.fnk
face: face/grapefruit_480.cpu.fnk
gender: faceattr/gender.v2.cpu.fnk
beard: faceattr/beard.v0.cpu.fnk
glasses3: faceattr/glasses3.v0.cpu.fnk
The following models are available:
Note
You can find face features recognition models at /usr/share/findface-data/models/faceattr/.
ls /usr/share/findface-data/models/faceattr/

Tip
To disable a recognition model, simply pass an empty value to a relevant parameter. Do not remove the parameter itself as in this case the system will be searching for the default model.
