Motion detection can be effectively implemented using background subtraction techniques. OpenCV provides several methods for this, such as MOG2 and KNN. Below is a straightforward example using MOG2:
language="language-python"import cv2
language="language-python"cap = cv2.VideoCapture(0) # Use 0 for webcam
language="language-python"backSub = cv2.createBackgroundSubtractorMOG2()
language="language-python"while True:-a1b2c3- ret, frame = cap.read()-a1b2c3- if not ret:-a1b2c3- break-a1b2c3--a1b2c3- # Apply background subtraction-a1b2c3- fgMask = backSub.apply(frame)-a1b2c3--a1b2c3- # Display the results-a1b2c3- cv2.imshow('Frame', frame)-a1b2c3- cv2.imshow('FG Mask', fgMask)-a1b2c3--a1b2c3- if cv2.waitKey(30) & 0xFF == 27: # Press 'Esc' to exit-a1b2c3- break-a1b2c3--a1b2c3-cap.release()-a1b2c3-cv2.destroyAllWindows()
This code captures video from the webcam, applies background subtraction, and displays the original frame alongside the foreground mask, effectively highlighting the detected motion.
