Age and Gender Recognition - Python example

Introduction

A Python example for using Spectrico's age and gender classifier. It consists of a face detector for finding the faces, and a classifier to recognize the age and the gender of the detected faces. The face detector is an implementation of MTCNN (Tensorflow backend). The classifier is based on MobileNet (Tensorflow backend). Tested under Windows 10 and Ubuntu.

There is a paid version with better accuracy. Here is a web demo to test it: Age and Gender Recognition

Usage

$ python age_gender_demo.py

Dependencies

pip install numpy

pip install opencv-python

pip install tensorflow

If you use Windows, the OpenCV package is recommended to be installed from: https://www.lfd.uci.edu/~gohlke/pythonlibs/
