What is Face-Api in ml5.js?
ml5.js has created an API to face-api.js that allows you to access face and face landmark detection.
Face API
The ml5.js implementation of face-api does not support expressions, age or gender estimation.
 
Quickstart :
const detectionOptions = {
  withLandmarks: true,
  withDescriptors: false,
};
// Initialize the magicFeature
const faceapi = ml5.faceApi(detectionOptions, modelLoaded);

// When the model is loaded
function modelLoaded() {
  console.log('Model Loaded!');

  // Make some sparkles
  faceapi.detect(myImage, (err, results) => {
    console.log(results);
  });
}
 
Usage :
Initialize :
const faceapi = ml5.faceApi(videoOrOptionsOrCallback, optionsOrCallback?, callback?);
Parameters :
* videoOrOptionsOrCallback : REQUIRED. Notice there is no question mark in front of the input.
 
* optionsOrCallback : OPTIONAL. Notice the ? indicates an optional parameter.
 
* callback : OPTIONAL. A description of some kind of object with some properties. Notice the ? indicates an optional parameter.
