Steam Face Detection

This repository contains Python code to detect faces on Steam store/library images.

Usage

Acquire the data, e.g. as a snapshot called 256x256.zip in one of my data repositories (here or there),
Run detect_faces_on_steam_banners.ipynb to detect (and count) faces.

NB: In order to try and adjust parameters, I suggest that you experiment with benchmark_face_detection.ipynb.

Data

The dataset consists of 14k vertical images, resized from 300x450 to 256x256 resolution, used by the Steam library.

Images were downloaded with download_steam_banners.ipynb.

Images were then filtered (duplicates, outliers, etc.) with remove_duplicates.ipynb.

Recommendations

I have used 3 tools for face detection:

dlib, which I used in another one of my projects,
face-alignment,
retinaface, available on PyPI.

Overall, I would recommend to use face-alignment over dlib as:

it detects more faces on Steam images, which feature difficult faces (hand-drawings, anime, 3D models, etc.),
it is about 3.5 times faster.

RetinaFace can detect even more faces, but it is slower than face-alignment.

Results

Overall, most images do not feature any detected face. Among images with faces, most images feature a single face. The more detected faces, the fewer images.
