So, Today I wanted to experiment with Simple OpenCV. So that the following script does is,
it loads the video from the disk, checks for face shape in every frame using the loaded cascade. if it finds an image, it draws a rectangle around it and displays the image. Unfortunately, it only detects frontal faces.
You can find the code to do this below

import cv2 # loading haarcascade to detect frontal face cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml') video = cv2.VideoCapture('data/avengers.mp4') # Load video while True: rect, img = video.read() # Read the video if not rect: break # Convert RGB to Gray to detect edges gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) faces = cascade.detectMultiScale(gray, 1.35, 7) # Detect possible faces if faces is not (): # List is not empty for x, y, w, h in faces: # Draw Rect in all faces cv2.rectangle(img, (x, y), (x+w, y+h), (127, 0, 255), 2) cv2.imshow('img', img) # Display the image k = cv2.waitKey(30) if k == 27: # if key pressed is escape quit break video.release() # release the video
