DFACE.app

DFACE Screenshot

DFACE.app is a web application that performs private, automatic face redaction in a web browser using YOLOv5 computer vision models and Tensorflow.js. Made by VFRAME.io.

Environment Setup

nvm use node
nvm install 14.17.1
nvm use 14.17.1
  • Install Yarn
npm install -g yarn
  • Install dependencies
yarn install
  • Disable Next.js telemetry:
npx next telemetry disable

Development

Start a development server on http://localhost:3000/

yarn dev

Models should be placed in public/assets/models/ in folders named identically to the names in modelzoo.yaml. The application will look for the file model.json when loading a model. The active models can be rebuilt from the YAML by running:

yarn modelzoo

Emoji

Let's admit it, emoji are probably the most important part of this application. Here is how you can generate a test document of emoji so you can load more (using twemoji):

cd node_modules/twemoji-emojis/vendor/svg
echo "<style>div img { width: 48px; height: 48px; display: block; } div { display: inline-block; font-size: 12px; }</style>" >> emoji.html
for i in *.svg; do echo "<div><img src="$i">$i</div>" >> emoji.html; done
python3 -m http.server 8000
  • Navigate to http://localhost:8000/emoji.html
  • Emoji are listed in components/common/Emoji.js, follow the pattern to add new ones
  • Emoji are grouped by classes. The list of classes should correspond to the emojiOptions in constants/index.js

Deployment

This command will build the static site to the out/ directory, suitable for deployment.

yarn build
