**deepface** is a lightweight python based facial analysis framework including face recognition and demography. You can use the framework with a just few lines of codes.
# Face Recognition
Verify function under the DeepFace interface is used for face recognition.

# Facial Attribute Analysis
Deepface also offers facial attribute analysis including [`age`](https://sefiks.com/2019/02/13/apparent-age-and-gender-prediction-in-keras/), [`gender`](https://sefiks.com/2019/02/13/apparent-age-and-gender-prediction-in-keras/), [`emotion`](https://sefiks.com/2018/01/01/facial-expression-recognition-with-keras/) and [`race`](https://sefiks.com/2019/11/11/race-and-ethnicity-prediction-in-keras/) predictions. Analysis function under the DeepFace interface is used to find demography of a face.
```python
from deepface import DeepFace
demography = DeepFace.analyze("img.zip") #passing nothing as 2nd argument will find everything
#demography = DeepFace.analyze("img.zip", ['age', 'gender', 'race', 'emotion']) #identical to above line
```
Analysis function returns a json object.
```

```
Then, you can retrieve the fields of the response object easily in Python.
```python
import json
print("Age: ",demography["age"])
return False
```
