- THREE.js based:
- SVG based:
- Native demos:
Run Locally
To run the library locally, you need to serve the content over an HTTPS server as follows:
1. Run: docker-compose up
2. Open a browser and go to localhost:8888Integration
Integrating the library into your existing project can be achieved in several ways:
With a Bundler
Use the module version and load the neural network model using AJAX. This ensures that unnecessary resources are only loaded when needed.
const faceExpressions = require('./lib/jeelizFaceExpressions.module.js');
const neuralNetworkModel = require('./dist/jeelizFaceExpressionsNNC.json');
faceExpressions.init({ NNC: neuralNetworkModel, ...other parameters });With JavaScript Frontend Frameworks
You can integrate it with popular frameworks like React, Vue, or Angular. While comprehensive examples aren’t provided, community-compiled resources can guide you.
Hosting
This library requires access to the user’s camera feed through the MediaStream API:
- Your application must be hosted over HTTPS.
- Ensure GZIP compression is enabled for faster load times.
About the Tech
Utilizing WebGL Deep Learning technology, the library detects and tracks user faces using a sophisticated neural network. The processing occurs entirely client-side, maximizing performance based on the user’s GPU capabilities.
Troubleshooting
If you encounter issues, here are some common troubleshooting tips:
- Ensure WebGL is supported on your browser. Test via caniuse.com.
- Check for conflicting applications that might be using your camera.
- Make sure you are running your application through HTTPS.
- For any compatibility issues, provide a screenshot of your WebGL implementation and the console logs.
