# Python code for object tracking
import cv2

# Initialize the tracker
tracker = cv2.TrackerKLT_create()

# Read the first frame
frame = cv2.imread('first_frame.jpg')

# Define the region of interest (ROI)
roi = (100, 100, 200, 200)  # Format: (x, y, width, height)

# Initialize the tracker with the first frame and ROI
tracker.init(frame, roi)

# Loop through subsequent frames and track the object
while True:
    # Read the next frame
    frame = cv2.imread('next_frame.jpg')

    # Update the tracker
    success, roi = tracker.update(frame)

    if success:
        # Draw a bounding box around the tracked object
        (x, y, w, h) = tuple(map(int, roi))
        cv2.rectangle(frame, (x, y), (x + w, y + h), (0, 255, 0), 2)
    else:
        # Object lost, handle the situation here
        pass

    # Display the frame
    cv2.imshow('Object Tracking', frame)

    # Exit the loop on key press (e.g., 'q')
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

# Release resources
cv2.destroyAllWindows()
