💻Basic OpenCV API with Django 📷

😈Face Detection API 😄

Resource :

I updated the code from PyImageSearch Blog to Python 3 and Django 3.

Creating a face detection API with Python and OpenCV (in just 5 minutes) - PyImageSearch

MVT (Model - View -Template)

Setup :

pip install numpy django requests

Create Project :

django-admin startproject face_api
cd face_api
code . # Visual Stusio Code

• create a new app named face_detector

python manage.py startapp face_detector

Create API :

• Edit views.py in face_detector

❗ ️ _grab_image is private function. Unable to run from outside the views.py file. you can move _grab_image to other file and setting with __all__ for change to public function.

❕ if you import module by :

from module_name import *

private variable , private class and private function are not imported

❕ if _ (single underscore) ➕ variable_name ➡️ private variable

❕ if _ (single underscore) ➕ class_name ➡️ private class

❕ if _ (single underscore) ➕ function_name ➡️ private function

• Edit urls.py in face_api

Download and Import Face Detection Model

• Download : https://github.com/opencv/opencv/tree/master/data/haarcascades
• Import Model :

mkdir cascades

import model to cascades folder and edit code line 14 in file views.py

Test API :

python manage.py runserver

• access to http://127.0.0.1:8000/ or http://localhost:8000/

• Error code [404] because I have not set url path at /
• access to http://localhost:8000/face_detection/detect/

• if api can detect face on your image from HTTP POST, api will send result is true [JSON format]

{ success : true }
