If you’re looking to dive into augmented reality face filters, you’re in the right place! This lightweight JavaScript library leverages WebGL to detect and track faces in real-time, all from a camera video feed captured with WebRTC. In this guide, we’ll explore how to set it up, key features, and some troubleshooting tips.

Features
The library is packed with innovative features:
- Real-time face detection and tracking
- Face rotation and mouth opening detection
- Support for multiple faces
- Robust performance in various lighting conditions
- HD video acquisition and mobile-friendly
- Interfacing capabilities with 3D engines like THREE.js, BABYLON.JS, and A-FRAME
Get Started
To kick things off, you’ll need to include the main script of the library, and then set up your HTML page. Here’s a simple analogy to grasp the setup process:
Imagine you’re setting up a stage for a play. The library is like a director that manages everything that happens on stage (your video feed). You’ll need a stage (the canvas) where the actors (the 3D content) will perform their role. Here’s how you can do it:
<html>
<head>
<script src="dist/jeelizFaceFilter.js"></script>
</head>
<body>
<canvas width="600" height="600" id="jeeFaceFilterCanvas"></canvas>
<script>
JEELIZFACEFILTER.init({
canvasId: "jeeFaceFilterCanvas",
NNCPath: "neuralNets/NN_DEFAULT.json",
callbackReady: function(errCode, spec) {
if (errCode) {
console.log("AN ERROR HAPPENS. ERROR CODE =", errCode);
return;
}
console.log("INFO: JEELIZFACEFILTER IS READY");
},
callbackTrack: function(detectState) {
// Render your AR scene here
}
});
</script>
</body>
</html>Troubleshooting
Here are some common issues and their fixes:
- GL_INCOMPATIBLE: This means your WebGL setup isn’t compatible. Ensure your browser supports WebGL2.
- WEBCAM_UNAVAILABLE: If this error appears, check if your camera is accessible or in use by another application.
- INVALID_CANVASID: Ensure that the canvas ID you provided matches the one in your HTML.
