Description

With ref https://github.com/justadudewhohacks/face-api.js#face-recognition-by-matching-descriptors

I've managed to train the faces and and saving the dataset with JSON.stringify(labelledDescriptors) to a static JSON.

Is there a way to quickly load this dataset, or do I have to load the raw JSON and reinit the dataset with each new faceapi.LabeledFaceDescriptors(name, descriptors)?

Is there method such as

const labelledDescriptors = await faceapi.fetchDescriptors('/files/labeledDescriptors.json');
const faceMatcher = new faceapi.FaceMatcher(labelledDescriptors);

Pardon, if I didn't explain myself well. But the objective is to quickly loaded a saved labeledDescriptors for usage.

Contributor guide

Research direction
Examine the LabeledFaceDescriptors constructor and the FaceMatcher class. Check if there is an existing fromJSON or static method to load descriptors from a plain object. If not, implement a static fromJSON method that accepts an array of objects with label and descriptors fields, returning an array of LabeledFaceDescriptors.
