FaceAPI

Note

This is updated face-api.js with latest available TensorFlow/JS as the original face-api.js is not compatible with tfjs 2.0+.

Forked from face-api.js version 0.22.2 released on March 22nd, 2020

• https://github.com/justadudewhohacks/face-api.js
• https://www.npmjs.com/package/face-api.js

Currently based on TensorFlow/JS 2.6.0
If you want to access TFJS classes and methods directly, they are exported as faceapi.tf

Differences

• Updated all type castings for TypeScript type checking to TypeScript 4.1
• Typescript build process now targets ES2018 and instead of dual ES5/ES6
• Compatible with TensorFlow/JS 2.0+
• Removed old tests, docs, examples
• Removed unnecesary package dependencies (karma, jasmine, etc.)
• Updated all package dependencies
• Browser bundle process uses ESBuild instead of Rollup
• New TensorFlow/JS dependencies since backends were removed from @tensorflow/tfjs-core
• Updated mobileNetv1 model due to batchNorm() dependency
• Fully tree shakable when imported as an ESM module
• Added version class that returns JSON object with version of FaceAPI as well as linked TFJS
• Removed following models as they are either obsolete or non-functional with tfjs 2.0+
  • mtcnn: Obsolete
  • tinyYolov2: Non-functional since weights are missing

Which means valid models are tinyFaceDetector and mobileNetv1

Installation

There are several ways to use Face-API:

1. IIFE script

Recommened for quick tests and backward compatibility with older Browsers that do not support ESM such as IE

This is simplest way for usage within Browser
Simply download dist/face-api.js, include it in your HTML file & it's ready to use

<script src="dist/face-api.js"><script>

IIFE script auto-registers global namespace faceapi within Window object which can be accessed directly from a <script> tag or from your JS file.

2. ESM module

Recommended for usage within Browser

2.1 Directly

To use ESM import directly in a Browser, you must import your script (e.g. index.js) with a type="module"

  <script src="./index.js" type="module">

and then in your index.js

  import * as faceapi from 'dist/face-api.esm.js';

2.2 With Bundler

Same as above, but expectation is that you'll package your script using a bundler such as webpack, rollup or esbuild in which case, you do not need to import a script as module - that depends on your bundler configuration

  import * as faceapi from 'dist/face-api.esm.js';

3. NPM module

3.1 Import ESM

Recommended for NodeJS projects

Install with:

  npm install @vladmandic/face-api 

And then use with:

  import * as faceapi from '@vladmandic/face-api';

Alternatively, if you have issues, force ESM import using

  import * as faceapi from '@vladmandic/face-api/dist/face-api.esm.js';

3.2. Import Sources

Recommended for complex NodeJS projects that use TFJS for other purposes and not just FaceaPI

This way you're importing FaceAPI sources directly and not a bundle, so you have to import @tensorflow/tfjs explicitly

3.2.1 For JavaScript projects

  import * as tf from '@tensorflow/tfjs';
  import * as faceapi from '@vladmandic/face-api/build/index.js';

3.2.2 For TypeScript projects

  import * as tf from '@tensorflow/tfjs';
  import * as faceapi from '@vladmandic/face-api/src/index.ts';

Weights

Pretrained models and their weights are includes in ./model.

Build

If you want to do a full rebuild, either download npm module

npm install @vladmandic/face-api
cd node_modules/@vladmandic/face-api

or clone a git project

git clone https://github.com/vladmandic/face-api
cd face-api

Then install all dependencies and run rebuild:

npm install
npm run build

Which will compile everything in ./src into ./build and create both ESM (standard) and IIFE (minified) bundles as well as sourcemaps in ./dist

Documentation

For documentation refer to original project at https://github.com/justadudewhohacks/face-api.js

Example

Single new example that uses both models as well as all of the extensions is included in /example/index.html
Example can be accessed directly using Git pages using URL: https://vladmandic.github.io/face-api/example/
