Real-Time Left Eye Detection OpenCV Python With Source Code

The Real-Time Left Eye Detection OpenCV Python was developed using Python OpenCV, In this article the system can detect the eye of a human in real-time using a web camera.

A Left Eye Detection OpenCV Python’s most successful application of eye detection would probably be photo taking. When you take a photo of your friends, the eye detection algorithm built into your digital camera detects where the eyes are and adjusts the focus accordingly.

while True:
    # Read the frame
    _, img = cap.read()
    # Convert to grayscale
    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
    # Detect the faces
    faces = face_cascade.detectMultiScale(gray, 1.1, 4)
    # Draw the rectangle around each face
    for (x, y, w, h) in faces:
        cv2.rectangle(img, (x, y), (x + w, y + h), (255, 0, 0), 2)
    # Display
