Convolutional Neural Network (CNN).

This repository contains a source code of a deep learning network built with TensorFlow and Keras to classify gender and estimate age.

Dataset

UTKFace. Large Scale Face Dataset

1. Download the file containing Aligned&Cropped Faces archive. The repository contains 23,708 images with annotations encoded in the filename. All images have 200*200 px resolution.
2. Unpack the contents into the ./src/all_images folder.

Example input images with actual gender and age:

Application

1. Create and activate a virtual environment.
2. Install project dependencies with pip install -r requirements.txt
3. Run the start.py file.
4. When running for the first time, select option 1 to split the images into train, validation and test subfolders. There is no need to repeat this operation every time.
5. The main menu includes an option to check if your system supports GPU training.
6. A pre-trained model is included in the /.output/models folder. Feel free to overwrite or delete it.

Inference

Run test the model option from main menu to load a few images and predict age and gender.

GPU Support

Tune down the batch_size hyperparameter if your GPU runs out of memory.

Tensorflow version that currently supports GPU with the latest CUDA / CUDNN.

pip install tf-nightly-gpu

Graphviz

You might require to install the Graphviz plotting library.
