Facemask Classifier Master

The Facemask Classifier Master is a computer vision application mainly used for facial recognition with the aim of identifying if an individual is wearing or not wearing a facemask. The application has been designed and developed to help in enforcing an essential aspect of public health and safety measures during the ongoing global pandemic by preventing the spread of the Covid-19 virus.

Key Features of Facemask Classifier Master

Some key features of the Facemask Classifier Master include:

Real-time capture

The Facemask Classifier Master can easily and quickly capture a real-time image or video of an individual's face.

Facemask detection

The Facemask Classifier Master can detect if an individual is wearing a facemask or not, and judge facial recognition accuracy based on these findings.

Easy to integrate

The Facemask Classifier Master can be easily integrated into various applications and platforms to help enforce mandatory mask-wearing in public places.

Code

import cv2
import numpy as np

face_classifier = cv2.CascadeClassifier('my_haarcascade_frontalface_default.xml')
mask_classifier = cv2.CascadeClassifier('my_haarcascade_mask.xml')

def detect_mask(frame):
    # Convert image to gray scale
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    # Detect faces in the image
    faces = face_classifier.detectMultiScale(gray, 1.3, 5)

    # Loop through each face
    for (x, y, w, h) in faces:
        # Gray-scale the face image
        face_gray = gray[y:y + h, x:x + w]

        # Detect masks in the face
        masks = mask_classifier.detectMultiScale(face_gray)

        # Check if a mask was detected
        if len(masks) == 0:
            return False

    return True

Conclusion

The Facemask Classifier Master is a powerful tool for facial recognition and detection of facemasks, which makes it an invaluable tool in enforcing crucial public health and safety measures during the pandemic. By integrating this application into various platforms, it is now possible to enforce the mandatory facemask-wearing measures in public places, which is highly recommended by the World Health Organization (WHO) and national health authorities in many countries.
