DeepPrivacy

[Interactive Demo]

Check out the new DeepPrivacy2! It significantly improves anonymization quality compared to this repository.

DeepPrivacy is a fully automatic anonymization technique for images.

This repository contains the source code for the paper "DeepPrivacy: A Generative Adversarial Network for Face Anonymization" published at ISVC 2019, and  "Image Inpainting with Learnable Feature Imputation " published at GCPR 2020.

The DeepPrivacy GAN never sees any privacy sensitive information, ensuring a fully anonymized image. It utilizes bounding box annotation to identify the privacy-sensitive area, and sparse pose information to guide the network in difficult scenarios.

DeepPrivacy detects faces with state-of-the-art detection methods. Mask R-CNN is used to generate a sparse pose information of the face, and DSFD is used to detect faces in the image.

Information

Check out the original version here:

Check out GCPR readme to reproduce our results from our publication "Image Inpainting with Learnable Feature Imputation".

New features in version 2

• FP16 inference
• Support for face detection and landmark detection with a single SSD model (retinanet).
• Face alignment before anonymization - improves performance for rotate faces.
• Heavily refactored code.
• All improvements from our paper "Image Inpainting with Learnable Feature Imputation" are included.
• Support for standard image inpainting datasets (CelebA-HQ and Places2).
• Support for video inference

Installation

Install the following:

• Pytorch >= 1.7.0 (Some checkpoints requires a bug fix from pytorch 1.7 - the current master branch)
• Torchvision >= 0.6.0
• NVIDIA Apex (If you want to train any models - nolt needed for inference)
• Python >= 3.6

Simply by running our setup.py file:

python3 setup.py install

or with pip:

pip install git+https://github.com/hukkelas/DeepPrivacy/

Docker

In our experiments, we use docker as the virtual environment.

Our docker image can be built by running:

cd docker/

docker build -t deep_privacy . 

Usage

We have a file command line interface to anonymize images.

python3 anonymize.py -s input_image.png -t output_path.png

You can change the model with the "-m" or "--model" flag (see model zoo). The cli accepts image files, video files, and directories.

The cli is also available outside the folder python -m deep_privacy.cli.

Also check out python -m deep_privacy.cli -h for more arguments.

Webcam

Test out the model with

python webcam.py

Also check out python webcam.py -h for more arguments.

Anonymization Model Zoo

Retinanet Detector

Combined keypoint and face detection in one single-shot model (SSD-based). Uses five landmarks: eyes, nose, and mouth (left and right). Model is based on RetinaFace. The model is significantly faster, but has poorer detection than DSFD.

DSFD + RCNN

Uses Mask R-CNN is for keypoint detection, and DSFD for face detection.
