#03- Image Processing - Face Detection . التعرف على الوجوه

I have used Python numPy and OpenCV to perform a face and eye recognition algorithm.. it is considered my first attempt but I will be working more isA . 


and here is the code: 



import cv2
import numpy as np


face_cascade = cv2.CascadeClassifier('E://haarcascade_frontalface_default.xml')
eye_cascade = cv2.CascadeClassifier('E://haarcascade_eye.xml')

cap = cv2.VideoCapture(0)

while True:
    ret, img = cap.read()
    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
    faces = face_cascade.detectMultiScale(gray, 1.3, 5)
    for(x,y, w,h) in faces:
        cv2.rectangle(img, (x,y), (x+w, y+h), (255,255,255), 1)
        roi_gray = gray[y:y+h, x:x+w]
        roi_color = img[y:y+h, x:x+w]
        eyes = eye_cascade.detectMultiScale(roi_gray)
        for(ex, ey, ew, eh) in eyes:
            cv2.rectangle(roi_color, (ex, ey), (ex+ew, ey+eh), (0, 0, 0), 1)
    cv2.imshow('img', img)
    k=cv2.waitKey(30) & 0xff
    if k==27:
        break
    
cap.release()
cv2.destroyAllWindows()
