Face Detection App in Just 5 Minutes | OpenCV Project
In this tutorial, I have touched you, how to create a Face Detection App in only 5 Minutes. Its computer vision Artificial Intelligence project and I used OpenCV Python Library and Cascade Classifier.

Face Detection App Project Code
# import OpenCV import cv2 # Load trained cascade classifier face_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml') # Read the given image color_image = cv2.imread('girl.png') # Convert color image into grayscale gray_image = cv2.cvtColor(color_image, cv2.COLOR_BGR2GRAY) # Detect faces ROI #Syntax: Classifier.detectMultiScale(input image, Scale Factor , Min Neighbors) faces = face_cascade.detectMultiScale(gray_image, 1.1, 5) # Draw rectangle around the faces for (x, y, w, h) in faces: cv2.rectangle(color_image, (x, y), (x + w, y + h), (0, 0, 255), 4) # Show image cv2.imshow('Image', color_image) #wait to close window cv2.waitKey() #close all windows cv2.destroyAllWindows()
