Cartooning A Webcam Stream With Python’s OpenCV



import cv2
# Create a VideoCapture object and read from input file
# If the input is the camera, pass 0 instead of the video file name
webcam = cv2.VideoCapture(0)
# Check if camera opened successfully
if (webcam.isOpened()== False): 
  print("Error opening video stream or file")
# Read the video
  # Capture frame-by-frame
  ret, frame =
  if ret == True:
  	color = cv2.bilateralFilter(frame, 9, 9, 7)
  	gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
  	blur = cv2.medianBlur(gray, 7)
  	edges = cv2.adaptiveThreshold(blur, 255, cv2.ADAPTIVE_THRESH_MEAN_C, cv2.THRESH_BINARY, 9, 2)
  	frame_edge = cv2.cvtColor(edges, cv2.COLOR_GRAY2RGB)
  	cartoon = cv2.bitwise_and(color, frame_edge)

  	# Display the resulting frame
  	cv2.imshow('Cartoonized', cartoon)
  	# Press Q on keyboard to  exit
  	if cv2.waitKey(25) & 0xFF == ord('q'):
  	# Break the loop
# When everything done, release the video capture object
# Closes all the frames
