More about Retinaface

Retinaface is the State-of-the-art for Face Detection on WIDER Face. There are two versions of retinaface: MobileNet Backend and Resnet Backend. The model using MobileNet as backbone has only 1.7M, the other model with Resnet backbone has ~30m. Here is the performance on the FDDB dataset:

FDDB(pytorch)	performance
Mobilenet0.25	98.64%
Resnet50	99.22%

---

Installation

$ pip install Pytorch-detection==0.0.1

---

Usage

from retinaface import RetinafaceDetector
import cv2 as cv


### Mobinet backbone 
detector  = RetinafaceDetector(net='mnet').detect_faces
img  = cv.imread('./imgs/DSC_8221.jpg')
bounding_boxes, landmarks = detector(img)
print(bounding_boxes)

### Resnet backbone 
detector  = RetinafaceDetector(net='rnet').detect_faces
img  = cv.imread('./imgs/DSC_8221.jpg')
bounding_boxes, landmarks = detector(img)
print(bounding_boxes)

How to make a python package

To create this project locally, create the following file structure:

retinaface
    ├── retinaface
    │      ├── __init__.py
    ├── LICENSE
    ├── README.md
    ├── setup.py
    ├── setup.py
    ├── requirements.txt

Creating setup.py

setup.py is the build script for setuptools. It tells setuptools about your package

import setuptools

setuptools.setup(
    name="Pytorch-detection", # Replace with your own username
    version="0.0.1",
    author="Hoang Phuong",
    author_email="hphuongdhsp@gmail.com",
    license='MIT',
    description = "A simple example package for face detection",
    long_description = long_description,
    long_description_content_type="text/markdown",
    url="https://github.com/hphuongdhsp/retinaface",
    packages=setuptools.find_packages(),
    classifiers=[
        "Programming Language :: Python :: 3",
        "License :: OSI Approved :: MIT License",
        "Operating System :: OS Independent",
    ],
    keywords='face detection, retinaface',
    install_requires=open('requirements.txt').readlines(),
    python_requires='>=3.6',
)

Creating README.md

Creating a LICENSE

Generating distribution archives

Install setuptools and wheel

$ pip install --user --upgrade setuptools wheel

make distribution files:

python3 setup.py sdist bdist_wheel

That command genetate two files in the dist directory:

   dist
    ├── Pytorch_detection-0.0.1-py3-none-any.whl
    ├── Pytorch-detection-0.0.1.tar.gz

Test in local

$ pip install -e .

Uploading the distribution archives

First, make sure that you have an accout on Test PyPI. To register an account, go to https://test.pypi.org/account/register/. Then create a PyPI API token

Install twine to to upload the distribution packages

$ sudo apt-get install -y twine

Run twine to upload all of the archives under dist:

$ python3 -m twine upload --repository testpypi dist/*

Output

To upload your work to PyPi

To upload your package to PyPI, we can do similar way:

• Register an account on https://pypi.org

• Use twine

python3 -m twine upload dist/*

to upload your package and enter your credentials for the account you registered on the real PyPI.

After uploading your work, you can install by

$ pip install Pytorch-detection==0.0.1
