FACENET

Build Status NPM Version Downloads Join the chat at https://gitter.im/node-facenet/Lobby node TypeScript

A TensorFlow backed FaceNet implementation for Node.js, which can solve face verification, recognition and clustering problems.

Google Facenet

FaceNet is a deep convolutional network designed by Google, trained to solve face verification, recognition and clustering problem with efficiently at scale.

  1. directly learns a mapping from face images to a compact Euclidean space where distances directly correspond to a measure of face similarity.
  2. optimize the embedding face recognition performance using only 128-bytes per face.
  3. achieves accuracy of 99.63% on Labeled Faces in the Wild (LFW) dataset, and 95.12% on YouTube Faces DB.

INSTALL

$ npm install facenet

EXAMPLE

The follow examples will give you some intuitions for using the code.

  1. demo exmaple will show you how to do align for face alignment and embedding to get face feature vector.
  2. visualize example will calculate the similarity between faces and draw them on the photo.

1. Demo for API Usage

TL;DR: Talk is cheap, show me the code!

import { Facenet } from 'facenet'

const facenet = new Facenet()

// Do Face Alignment, return faces
const imageFile = `${__dirname}/../tests/fixtures/two-faces.jpg`
const faceList = await facenet.align(imageFile)

for (const face of faceList) {
  console.log('bounding box:',  face.boundingBox)
  console.log('landmarks:',     face.facialLandmark)

  // Calculate Face Embedding, return feature vector
  const embedding = await facenet.embedding(face)
  console.log('embedding:', embedding)
}
faceList[0].embedding = await facenet.embedding(faceList[0])
faceList[1].embedding = await facenet.embedding(faceList[1])
console.log('distance between the different face: ', faceList[0].distance(faceList[1]))
console.log('distance between the same face:      ', faceList[0].distance(faceList[0]))

Full source code can be found at here: https://github.com/zixia/node-facenet/blob/master/examples/demo.ts

The output should be something like:

image file: /home/zixia/git/facenet/examples/../tests/fixtures/two-faces.jpg
face file: 1-1.jpg
bounding box: {
  p1: { x: 360, y: 95 }, 
  p2: { x: 589, y: 324 } 
}
landmarks: { 
  leftEye:  { x: 441, y: 181 },
  rightEye: { x: 515, y: 208 },
  nose:     { x: 459, y: 239 },
  leftMouthCorner:  { x: 417, y: 262 },
  rightMouthCorner: { x: 482, y: 285 } 
}
embedding: array([ 0.02453, 0.03973, 0.05397, ..., 0.10603, 0.15305,-0.07288])

face file: 1-2.jpg
bounding box: { 
  p1: { x: 142, y: 87 }, 
  p2: { x: 395, y: 340 } 
}
landmarks: { 
  leftEye:  { x: 230, y: 186 },
  rightEye: { x: 316, y: 197 },
  nose:     { x: 269, y: 257 },
  leftMouthCorner:  { x: 223, y: 273 },
  rightMouthCorner: { x: 303, y: 281 } 
}
embedding: array([ 0.03241, -0.0737,  0.0475, ..., 0.07235, 0.12581,-0.00817])

2. Visualize for Intuition

FaceNet Visualization

  1. Face is in the green rectangle.
  2. Similarity(distance) between faces showed as a number in the middle of the line.
  3. To identify if two faces belong to the same person, we could use an experiential threshold of distance: 0.75.
$ git clone [email protected]:zixia/node-facenet.git
$ cd facenet
$ npm install
$ npm run example:visualize

01:15:43 INFO CLI Visualized image saved to:  facenet-visulized.jpg

3. Get the diffence of two face

Get the two face's distance, the smaller the number is, the similar of the two face

import { Facenet } from 'facenet'

const facenet = new Facenet()
const imageFile = `${__dirname}/../tests/fixtures/two-faces.jpg`

const faceList = await facenet.align(imageFile)
faceList[0].embedding = await facenet.embedding(faceList[0])
faceList[1].embedding = await facenet.embedding(faceList[1])
console.log('distance between the different face: ', faceList[0].distance(faceList[1]))
console.log('distance between the same face:      ', faceList[0].distance(faceList[0]))

Output:
distance between the different face: 1.2971515811057608
distance between the same face: 0

In the example,
faceList[0] is totally the same with faceList[0], so the number is 0
faceList[1] is different with faceList[1], so the number is big.
If the number is smaller than 0.75, maybe they are the same person.

4. Save the face picture from a picture

Recognize the face and save the face to local file.

import { Facenet } from 'facenet'

const facenet = new Facenet()
const imageFile = `${__dirname}/../tests/fixtures/two-faces.jpg`

const faceList = await facenet.align(imageFile)
for (const face of faceList) {
  await face.save(face.md5 + '.jpg')
  console.log(`save face ${face.md5} successfuly`)
}
console.log(`Save ${faceList.length} faces from the imageFile`)

Full source code can be found at here: https://github.com/zixia/node-facenet/blob/master/examples/get-face.ts

FACENET MANAGER

UNDER HEAVY DEVELOPMENT NOW

Roadmap: release facenet-manager on version 0.4

asciicast

The above ascii recording is just for demo purpose. Will replace it with facenet-manager later.

DOCUMENT

See auto generated docs

INSTALL & REQUIREMENT

$ npm install facenet

OS

Supported:

  • Linux
  • Mac
  • Windows

Dependency

  1. Node.js >= 7 (8 is recommend)
  2. Tensorflow >= 1.2
  3. Python3 >=3.5 (3.6 is recommend)

Make sure you run those commands under Ubuntu 17.04:

sudo apt install python3-pip
pip3 install setuptools --upgrade

Ram

Neural Network Model Task Ram
MTCNN Facenet#align() 100MB
Facenet Facenet#embedding() 2GB

If you are dealing with very large images(like 3000x3000 pixels), there will need additional 1GB of memory.

So I believe that Facenet will need at least 2GB memory, and >=4GB is recommended.

API

Neural Network alone is not enough. It's Neural Network married with pre-trained model, married with easy to use APIs, that yield us the result that makes our APP sing.

Facenet is designed for bring the state-of-art neural network with bleeding-edge technology to full stack developers.

Facenet

import { Facenet } from 'facenet'

const facenet = new Facenet()
facenet.quit()

1. Facenet#align(filename: string): Promise<Face[]>

Do face alignment for the image, return a list of faces.

2. Facenet#embedding(face: Face): Promise<FaceEmbedding>

Get the embedding for a face.

face.embedding = await facenet.embedding(face)

Face

Get the 128 dim embedding vector for this face.(After alignment)

import { Face } from 'facenet'

console.log('bounding box:',  face.boundingBox)
console.log('landmarks:',     face.facialLandmark)
console.log('embedding:',     face.embedding)

ENVIRONMENT VARIABLES

It seems the package not installed in a right way, like sharp, canvas, remove the package and reinstall it.

run

rm -rf node node_modules/canvas
// if sharp, then remove sharp folder
npm install
  1. Error when install

x model-20170512-110547.ckpt-250000.data-00000-of-00001: (Empty error message)
tar: Error exit delayed from previous errors.

It seems this because not get the full model file successfully. See #issue63

Solution:

download the file from https://github.com/zixia/node-facenet/releases/download/v0.1.9/model-20170512.tar.bz2
rename the file model.tar.bz2 and move it to the folder models try npm install again
