2. Python programming with Open CV Page 2 1.The Face & Eyes Detection Step1: Open The Pycharm IDE

3. Python programming with Open CV Page 3 Step2: Source Code import numpy as np import cv2 #Import Open Source Computer Vision Package face_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml') eye_cascade = cv2.CascadeClassifier('haarcascade_eye.xml') cap = cv2.VideoCapture(0) #Capture video from front camera of our laptop while 1: ret, img = cap.read() gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) #By default in CV the image is read in BGR format 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, 0, 0), 2) #Rectangular box size initialization 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, 255, 0), 2) cv2.imshow('img', img) k = cv2.waitKey(30) & 0xff # cv2.waitKey() will show the image for assigned time duration if k == 27: #If user presses Esc Key then video capturing will be terminated break cap.release() #Its mandatory to release video capture cv2.destroyAllWindows()#Once the task completes then we will close all the opened windows Step3: Run the code Result: 1. Showing my face and eyes detected and enclosed in a box

4. Python programming with Open CV Page 4 2. Showing face and eyes of mine and the person in my cell phone and also in photo detected and enclosed in a box

5. Python programming with Open CV Page 5 2. Nose Detection of Human Source Code: import cv2 import numpy as np nose_cascade = cv2.CascadeClassifier('haarcascade_mcs_nose.xml') cap = cv2.VideoCapture(0) ds_factor = 0.5 while True: ret, frame = cap.read() frame = cv2.resize(frame, None, fx=ds_factor, fy=ds_factor, interpolation=cv2.INTER_AREA) gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY) nose_rects = nose_cascade.detectMultiScale(gray, 1.3, 5) for (x,y,w,h) in nose_rects: cv2.rectangle(frame, (x,y), (x+w,y+h), (0,255,0), 3) break cv2.imshow('Nose Detected', frame) c = cv2.waitKey(1) if c == 27: break cap.release() cv2.destroyAllWindows() Result: Nose being detected

6. Python programming with Open CV Page 6 3. Mouth Detection of Human Source Code: import cv2 import numpy as np mouth_cascade = cv2.CascadeClassifier('haarcascade_mcs_mouth.xml') cap = cv2.VideoCapture(0) ds_factor = 0.5 while True: ret, frame = cap.read() frame = cv2.resize(frame, None, fx=ds_factor, fy=ds_factor, interpolation=cv2.INTER_AREA) gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY) mouth_rects = mouth_cascade.detectMultiScale(gray, 1.7, 11) for (x,y,w,h) in mouth_rects: y = int(y - 0.15*h) cv2.rectangle(frame, (x,y), (x+w,y+h), (0,255,0), 3) break cv2.imshow('Mouth Detected', frame) c = cv2.waitKey(1) if c == 27: break cap.release() cv2.destroyAllWindows() Result: Mouth being detected
