Face Detection (Cascade Method)

VIOLA & JONES

I have used cascade method (Probably I'm not ready for deep learning methods 😂 ). First real-time object detection method was created by Viola&Jones (2001)

import cv2
import numpy as np

faceCascade = cv2.CascadeClassifier("Resources/haarcascade_frontalface_default.xml")
img = cv2.imread("Resources/lena.png")
imgGray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
faces = faceCascade.detectMultiScale(imgGray, 1.1, 4)

for (x,y,w,h) in faces:
    cv2.rectangle(img, (x, y), (x+w, y+h), (255, 0, 0), 2, cv2.LINE_4)

cv2.imshow("Output", img)
cv2.waitKey(0)
