Overview

Face Recognition

You can also read a translated version of this file in Chinese 简体中文版 or in Korean 한국어 or in Japanese 日本語.

Recognize and manipulate faces from Python or from the command line with the world's simplest face recognition library.

Built using dlib's state-of-the-art face recognition built with deep learning. The model has an accuracy of 99.38% on the Labeled Faces in the Wild benchmark.

This also provides a simple face_recognition command line tool that lets you do face recognition on a folder of images from the command line!

Features

Find faces in pictures

Find all the faces that appear in a picture:

import face_recognition
image = face_recognition.load_image_file("your_file.jpg")
face_locations = face_recognition.face_locations(image)

Find and manipulate facial features in pictures

Get the locations and outlines of each person's eyes, nose, mouth and chin.

import face_recognition
image = face_recognition.load_image_file("your_file.jpg")
face_landmarks_list = face_recognition.face_landmarks(image)

Finding facial features is super useful for lots of important stuff. But you can also use it for really stupid stuff like applying digital make-up (think 'Meitu'):

Identify faces in pictures

Recognize who appears in each photo.

import face_recognition
known_image = face_recognition.load_image_file("biden.jpg")
unknown_image = face_recognition.load_image_file("unknown.jpg")

biden_encoding = face_recognition.face_encodings(known_image)[0]
unknown_encoding = face_recognition.face_encodings(unknown_image)[0]

results = face_recognition.compare_faces([biden_encoding], unknown_encoding)

You can even use this library with other Python libraries to do real-time face recognition:

See this example for the code.

Usage

Command-Line Interface

When you install face_recognition, you get two simple command-line programs:

face_recognition - Recognize faces in a photograph or folder full for photographs.
face_detection - Find faces in a photograph or folder full for photographs.

`face_recognition` command line tool

The face_recognition command lets you recognize faces in a photograph or folder full for photographs.

First, you need to provide a folder with one picture of each person you already know. There should be one image file for each person with the files named according to who is in the picture:

Next, you need a second folder with the files you want to identify:

Then in you simply run the command face_recognition, passing in the folder of known people and the folder (or single image) with unknown people and it tells you who is in each image:

$ face_recognition ./pictures_of_people_i_know/ ./unknown_pictures/

/unknown_pictures/unknown.jpg,Barack Obama
/face_recognition_test/unknown_pictures/unknown.jpg,unknown_person

There's one line in the output for each face. The data is comma-separated with the filename and the name of the person found.

An unknown_person is a face in the image that didn't match anyone in your folder of known people.

`face_detection` command line tool

The face_detection command lets you find the location (pixel coordinatates) of any faces in an image.

Just run the command face_detection, passing in a folder of images to check (or a single image):

$ face_detection  ./folder_with_pictures/

examples/image1.jpg,65,215,169,112
examples/image2.jpg,62,394,211,244
examples/image2.jpg,95,941,244,792

It prints one line for each face that was detected. The coordinates reported are the top, right, bottom and left coordinates of the face (in pixels).

Adjusting Tolerance / Sensitivity

If you are getting multiple matches for the same person, it might be that the people in your photos look very similar and a lower tolerance value is needed to make face comparisons more strict.

You can do that with the --tolerance parameter. The default tolerance value is 0.6 and lower numbers make face comparisons more strict:

$ face_recognition --tolerance 0.54 ./pictures_of_people_i_know/ ./unknown_pictures/

/unknown_pictures/unknown.jpg,Barack Obama
/face_recognition_test/unknown_pictures/unknown.jpg,unknown_person

If you want to see the face distance calculated for each match in order to adjust the tolerance setting, you can use --show-distance true:

$ face_recognition --show-distance true ./pictures_of_people_i_know/ ./unknown_pictures/

/unknown_pictures/unknown.jpg,Barack Obama,0.378542298956785
/face_recognition_test/unknown_pictures/unknown.jpg,unknown_person,None

More Examples

If you simply want to know the names of the people in each photograph but don't care about file names, you could do this:

$ face_recognition ./pictures_of_people_i_know/ ./unknown_pictures/ | cut -d ',' -f2

Barack Obama
unknown_person

Speeding up Face Recognition

Face recognition can be done in parallel if you have a computer with multiple CPU cores. For example, if your system has 4 CPU cores, you can process about 4 times as many images in the same amount of time by using all your CPU cores in parallel.

If you are using Python 3.4 or newer, pass in a --cpus <number_of_cpu_cores_to_use> parameter:

$ face_recognition --cpus 4 ./pictures_of_people_i_know/ ./unknown_pictures/

You can also pass in --cpus -1 to use all CPU cores in your system.

Python Module

You can import the face_recognition module and then easily manipulate faces with just a couple of lines of code. It's super easy!

API Docs: https://face-recognition.readthedocs.io.

Automatically find all the faces in an image

import face_recognition

image = face_recognition.load_image_file("my_picture.jpg")
face_locations = face_recognition.face_locations(image)

# face_locations is now an array listing the co-ordinates of each face!

See this example to try it out.

You can also opt-in to a somewhat more accurate deep-learning-based face detection model.

Note: GPU acceleration (via NVidia's CUDA library) is required for good performance with this model. You'll also want to enable CUDA support when compliling dlib.

import face_recognition

image = face_recognition.load_image_file("my_picture.jpg")
face_locations = face_recognition.face_locations(image, model="cnn")

# face_locations is now an array listing the co-ordinates of each face!

See this example to try it out.

If you have a lot of images and a GPU, you can also find faces in batches.

Automatically locate the facial features of a person in an image

import face_recognition

image = face_recognition.load_image_file("my_picture.jpg")
face_landmarks_list = face_recognition.face_landmarks(image)

# face_landmarks_list is now an array with the locations of each facial feature in each face.
# face_landmarks_list[0]['left_eye'] would be the location and outline of the first person's left eye.

See this example to try it out.

Recognize faces in images and identify who they are

import face_recognition

picture_of_me = face_recognition.load_image_file("me.jpg")
my_face_encoding = face_recognition.face_encodings(picture_of_me)[0]

# my_face_encoding now contains a universal 'encoding' of my facial features that can be compared to any other picture of a face!

unknown_picture = face_recognition.load_image_file("unknown.jpg")
unknown_face_encoding = face_recognition.face_encodings(unknown_picture)[0]

# Now we can see the two face encodings are of the same person with `compare_faces`!

results = face_recognition.compare_faces([my_face_encoding], unknown_face_encoding)

if results[0] == True:
    print("It's a picture of me!")
else:
    print("It's not a picture of me!")

See this example to try it out.

Creating a Standalone Executable

If you want to create a standalone executable that can run without the need to install python or face_recognition, you can use PyInstaller. However, it requires some custom configuration to work with this library. See this issue for how to do it.

How Face Recognition Works

If you want to learn how face location and recognition work instead of depending on a black box library, read my article.

Caveats

The face recognition model is trained on adults and does not work very well on children. It tends to mix up children quite easy using the default comparison threshold of 0.6.
Accuracy may vary between ethnic groups. Please see this wiki page for more details.

Deployment to Cloud Hosts (Heroku, AWS, etc)

Since face_recognition depends on dlib which is written in C++, it can be tricky to deploy an app using it to a cloud hosting provider like Heroku or AWS.

To make things easier, there's an example Dockerfile in this repo that shows how to run an app built with face_recognition in a Docker container. With that, you should be able to deploy to any service that supports Docker images.

You can try the Docker image locally by running: docker-compose up --build

Linux users with a GPU (drivers >= 384.81) and Nvidia-Docker installed can run the example on the GPU: Open the docker-compose.yml file and uncomment the dockerfile: Dockerfile.gpu and runtime: nvidia lines.

Having problems?

If you run into problems, please read the Common Errors section of the wiki before filing a github issue.

Thanks

Many, many thanks to Davis King (@nulhom) for creating dlib and for providing the trained facial feature detection and face encoding models used in this library. For more information on the ResNet that powers the face encodings, check out his blog post.
Thanks to everyone who works on all the awesome Python data science libraries like numpy, scipy, scikit-image, pillow, etc, etc that makes this kind of stuff so easy and fun in Python.
Thanks to Cookiecutter and the audreyr/cookiecutter-pypackage project template for making Python project packaging way more tolerable.

Windows Installation Tutorial
Hi, I've successfully installed and tested this tool on my Windows 10 machine, and I'm writing a simple procedure to install it. It may be useful for some people to try to use this tool on a Windows machine.

IMPORTANT: Actually, this project has been done for Linux systems, especially dlib. In my tests, the performance of this tool in Windows 10 was about a quarter compared to Ubuntu, built with the same specs. But I haven't seen any difference between these two in other subjects.

Read First: The new version of dlib doesn't need Boost anymore, so you can skip it. Remember that you still need to meet the following requirements. Requirments: (I've used this tutorial with these tools installed on Windows 10, but the newer versions may work too.)

Microsoft Visual Studio 2015 (or newer) with C/C++ Compiler installed. (Visual C++ 2015 Build Tools didn't work for me, and I got into problems in compiling dlib)

Of course Python3 (I used Python3.5 x64 but the other versions may work too)

CMake for windows and add it to your system environment variables.

(ONLY FOR older versions of dlib) Boost library version 1.63 or newer. Also, you can use precompiled binaries for specific MSVC you have, but I don't suggest. (I've included the compiling procedure of Boost in this tutorial)

Installation: Easy installation: Just install dlib and face_recognition (not always on the newest version): pip install dlib and then pip install face_recognition.

Manual installation:

Download and install scipy and numpy+mkl (must be mkl version) packages from this link (all credits goes to Christoph Gohlke). Remember to grab the correct version based on your current Python version.

Download Boost library source code or binary release for your current MSVC from this link.

If you downloaded the binary version skip to step 4 else, follow these steps to compile and build Boost by yourself: 3-1. Extract the Boost source files into C:\local\boost_1_XX_X (X means the current version of Boost you have) 3-2. Create a system variable with these parameters: Name: VS140COMNTOOLS Value: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\ (or any path where you have installed MSVC) 3-3. Open Developer Command Prompt for Visual Studio and go to the current directory of Boost extracted and try these commands to compile Boost: bootstrap b2 -a --with-python address-model=64 toolset=msvc runtime-link=static 3-4. If you successfully compile Boost, it should create compiled files in stage directory.

(If you have already compiled Boost skip this step) If you already download the binary release, extract the contents to C:\local\boost_1_XX_X

Grab the latest version of dlib from this repo and extract it.

Go to dlibdirectory and open cmd and follow these commands to build dlib: (remember to replace XX with the current version of Boost you have) set BOOST_ROOT=C:\local\boost_X_XX_X set BOOST_LIBRARYDIR=C:\local\boost_X_XX_X\stage\lib python setup.py install --yes USE_AVX_INSTRUCTIONS or python setup.py install --yes USE_AVX_INSTRUCTIONS --yes DLIB_USE_CUDA

Now, you can use import dlib without any problem in your python script.

You can also check the current version of dlib with pip show dlib.

Now, install face_recognition with pip install face_recognition.

Enjoy!

Finally, I need to say thanks to @ageitgey and @davisking for their awesome work.

How can I make face recognition faster if I have more than 1M known images?

I tried to use your amazing project for face recognition (for example single unknown image) with my big number of known images (1 Million) but its really slow, this slow because its will load all known images (load_image_file -> then face_encodings) in order to compare with ONE unknown image file.

Any ideas how to speed this process? I was thinking to do face_encodings for all known images then save the 128 as string into apache solr but with no luck as I still need to do compare_faces with all known images:) ... Any suggestions?

Freeze your script with Pyinstaller

Hi, You might want to freeze your script into a standalone executable to run on any system without the need of installing python or face_recognition and maybe you want to create a demo for your application and want to give it to someone else without giving your source code. Here is a simple tutorial to do that. I tested this method with python3.6 on Windows 10, but I think you can get it working on Linux with a similar method.

Make sure you have correctly installed both face_recognition and dlib and you see no error when importing them into your script.
Make sure your script works fine, and all its dependencies are right next to it, and you can run it fine with python yourscript.py.
Install Pyinstallerwith pip: pip install pyinstaller
Create a new directory and move your python script and all dependencies into it. I call it myproject and myscript.py
Copy face_recognition_models and scipy-extra-dll from your python installed directory to your project directory.
Create an empty file called <yourscriptname>.spec like myscript.spec next to your python script.
Use below Pyinstaller spec file sample and edit some parts according to your needs: (I mark it with <> tag)

What is the expected speed per image?

First of all- this is awesome! Much better than OpenCV. No false positives so far while OpenCV had many. However it does about 1 image per second on my my Core i7. And I am just using face detection from this python library (no recognition). Is this a normal result? Feels a tad slow.

How to install face_recognition?

There is something seriously wrong with this script. I tried 2 methods and both gave me nothing. I am trying on Debian 8 Amd64.

Method 1 returns so many errors after the last command that it's insane:

apt-get install libcurl3
apt-get install cmake
apt-get install git
apt-get install python3.4
apt-get install python3-pip
apt-get install libboost-all-dev
mkdir temporarydir
cd temporarydir
git clone https://github.com/davisking/dlib.git
cd dlib
mkdir build 
cd build;
cmake .. -DDLIB_USE_CUDA=0 -DUSE_AVX_INSTRUCTIONS=1
cmake --build .
cd ..
python3 setup.py install --yes USE_AVX_INSTRUCTIONS --no DLIB_USE_CUDA
pip3 install scipy
pip3 install face_recognition

Method 2 is simpler:

wget https://3230d63b5fc54e62148e-c95ac804525aac4b6dba79b00b39d1d3.ssl.cf1.rackcdn.com/Anaconda-2.3.0-Linux-x86_64.sh
bash Anaconda-2.3.0-Linux-x86_64.sh
conda create -n py35 python=3.5
activate py35
conda config --add channels conda-forge
conda install numpy
conda install scipy
conda install dlib
pip install face_recognition
conda install scipy

As you can see I installed scipy twice and yet when I try to run face_recognition I get:

Need To Uninstall dlib and face_recognition, getting 'face_recognition' has no attribute 'load_image_file'
face_recognition version: The one on Github as of three days ago

Python version: 3.6

Operating System: Ubuntu

Description

face_recognition was working fine but then I tried to get dlib to use my GPU.
I uninstalled as much of the two (dlib and face_recognition) as a could, installed dlib so that it would use my GPU, re-installed face_recognition, but I clearly didn't have a clean enough uninstall. Now when I try to use face_recognition I'm getting...
$ python3 face.py Traceback (most recent call last): File "face.py", line 58, in image = face_recognition.load_image_file(aly) AttributeError: module 'face_recognition' has no attribute 'load_image_file'

I know the problem is not with my code because, like I said, I worked before and it was using the CPU. The trouble started when I tried to get it to use the GPU. I know I should have done a full uninstallation of dlib and face_recognition but I don't know how. Know face_recognition and dlib documentation or Q&A problems up on the Internet anywhere explain this in a way that I can find/ make use of.

Could you please help me uninstall these two modules, so I can get dlib re-installed the right way? Thank you.

In Face Detection process, is it possible to form/generate an image of person whose faces got matched either self/ matching with some other face model
face_recognition version: face_recognition-1.2.3

Python version: 3.9

Operating System: Linux distro, actually docker image : python:3.9-buster

Description

Describe what you were trying to get done : I have trained many people's face and stored their face-model with 128 nd array through pickle dump My detection is also working well, no issue with it When a person's face is recognized, I return the name of the person's even if I am getting multiple face found issues, but now I want to return the person's face to whomever it matches with. Please guide me through the conversion of face-model to image, any dlib-lib reference, or other would be a great help.

Fixed regression introduced in v0.38.1 which broke parsing of wheel file names with multiple platform tags

0.38.1 (2022-11-04)

Removed install dependency on setuptools

The future-proof fix in 0.36.0 for converting PyPy's SOABI into a abi tag was faulty. Fixed so that future changes in the SOABI will not change the tag.

0.38.0 (2022-10-21)

Dropped support for Python < 3.7

Updated vendored packaging to 21.3

Replaced all uses of distutils with setuptools

Unable to locate images

Description

So I am trying to train my model what multiple images using SVM's SVC classifier While training the model, The face_recognition.face_locations(img) function is unable to detect images in a phone captured image While it is able to detect images with the webcam captured image
I don't know what is wrong with it, the image quality on my phone is quit good as it has a 50MP camera Image details (will not be able to share the image due to confidentiality issues) type: JPEG width:2640px height:1188px Single face per single image

Unqiue ID per face?

More of a discussion, but is it possible to generate a unique ID from the facial recognition?

The use case is I will scan an amount of images, get the face ID for each face it recognizes, and put it in a database, then whenever i submit an input image, it will get the face ID from the input and if that matches with any in the database it shows the corresponding info or whatever.

is that possible with this? basically i'm asking if this code generates a unique ID for each unique face it detects. Is this value passed on somewhere? i can't see in the code what this value is saved as, if it does exist.
