# Face Recognition

Detect facial landmarks from Python using the world's most accurate face alignment network, capable of detecting points in both 2D and 3D coordinates.

Build using [FAN](https://www.adrianbulat.com)'s state-of-the-art deep learning based face alignment method. 

<p align="center"><img src="docs/images/face-alignment-adrian.gif" /></p>

**Note:** The lua version is available [here](https://github.com/1adrianb/2D-and-3D-face-alignment).

For numerical evaluations it is highly recommended to use the lua version which uses indentical models with the ones evaluated in the paper. More models will be added soon.

## Features

#### Detect 2D facial landmarks in pictures

<p align='center'>
<img src='docs/images/2dlandmarks.png' title='3D-FAN-Full example' style='max-width:600px'></img>
</p>

```python
import face_alignment
from skimage import io

fa = face_alignment.FaceAlignment(face_alignment.LandmarksType._2D, flip_input=False)

input = io.imread('../test/assets/aflw-test.jpg')
preds = fa.get_landmarks(input)
```

#### Detect 3D facial landmarks in pictures

<p align='center'>
<img src='https://www.adrianbulat.com/images/image-z-examples.png' title='3D-FAN-Full example' style='max-width:600px'></img>
</p>

```python
import face_alignment
from skimage import io

fa = face_alignment.FaceAlignment(face_alignment.LandmarksType._3D, flip_input=False)

input = io.imread('../test/assets/aflw-test.jpg')
preds = fa.get_landmarks(input)
```

#### Process an entire directory in one go

```python
import face_alignment
from skimage import io

fa = face_alignment.FaceAlignment(face_alignment.LandmarksType._2D, flip_input=False)

preds = fa.get_landmarks_from_directory('../test/assets/')
```

#### Detect the landmarks using a specific face detector.

By default the package will use the SFD face detector. However the users can alternatively use dlib or pre-existing ground truth bounding boxes.

```python
import face_alignment

# sfd for SFD, dlib for Dlib and folder for existing bounding boxes.
fa = face_alignment.FaceAlignment(face_alignment.LandmarksType._2D, face_detector='sfd')
```

#### Running on CPU/GPU
In order to specify the device (GPU or CPU) on which the code will run one can explicitly pass the device flag:

```python
import face_alignment

# cuda for CUDA
fa = face_alignment.FaceAlignment(face_alignment.LandmarksType._2D, device='cpu')
```

Please also see the ``examples`` folder

## Installation

### Requirements

* Python 3.5+ or Python 2.7 (it may work with other versions too)
* Linux, Windows or macOS
* pytorch (>=0.4)

While not required, for optimal performance(especially for the detector) it is **highly** recommended to run the code using a CUDA enabled GPU.

### Binaries

```bash
conda install -c 1adrianb face_alignment
```

### From source

 Install pytorch and pytorch dependencies. Instructions taken from [pytorch readme](https://github.com/pytorch/pytorch). For a more updated version check the framework github page.

 On Linux
```bash
export CMAKE_PREFIX_PATH="$(dirname $(which conda))/../" # [anaconda root directory]

# Install basic dependencies
conda install numpy pyyaml mkl setuptools cmake gcc cffi

# Add LAPACK support for the GPU
conda install -c soumith magma-cuda80 # or magma-cuda75 if CUDA 7.5
```

On OSX
```bash
export CMAKE_PREFIX_PATH=[anaconda root directory]
conda install numpy pyyaml setuptools cmake cffi
```
#### Get the PyTorch source
```bash
git clone --recursive https://github.com/pytorch/pytorch
```

#### Install PyTorch
On Linux
```bash
python setup.py install
```

On OSX
```bash
MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ python setup.py install
```


#### Get the Face Alignment source code
```bash
git clone https://github.com/1adrianb/face-alignment
```
#### Install the Face Alignment lib
```bash
pip install -r requirements.txt
python setup.py install
```

### Docker image

A Dockerfile is provided to build images with cuda support and cudnn v5. For more instructions about running and building a docker image check the orginal Docker documentation.
```
docker build -t face-alignment .
```

## How does it work?

While here the work is presented as a black-box, if you want to know more about the intrisecs of the method please check the original paper either on arxiv or my [webpage](https://www.adrianbulat.com).

## Contributions

All contributions are welcomed. If you encounter any issue (including examples of images where it fails) feel free to open an issue.
