cap = cv2.VideoCapture('input_video.mp4')
while cap.isOpened():
ret, frame = cap.read()
if not ret:
break
# Track objects in the current frame
boxes, ids = tracker.track(frame)
for box_id in zip(boxes, ids):
x1, y1, x2, y2, id = box_id
cv2.putText(frame, f'ID: {id}', (x1, y1 - 30), cv2.FONT_HERSHEY_SIMPLEX, 0.5, (0, 255, 0), 2)
# Display the frame with tracking results
cv2.imshow('ByteTrack', frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
Practical Examples
Example 1: Smart Surveillance System
In this scenario, ByteTrack is used to monitor a crowded area and identify potential security threats in real-time.
# Import necessary modules
from byte_track import ByteTracker
import cv2
# Initialize the tracking model
tracker = ByteTracker()
# Load an input video or frame sequence from a camera feed
cap = cv2.VideoCapture('surveillance_feed.mp4')
while cap.isOpened():
ret, frame = cap.read()
if not ret:
break
# Track objects in the current frame
boxes, ids = tracker.track(frame)
for box_id in zip(boxes, ids):
x1, y1, x2, y2, id = box_id
cv2.rectangle(frame, (x1, y1), (x2, y2), (0, 255, 0), 2)
cv2.putText(frame, f'ID: {id}', (x1, y1 - 30), cv2.FONT_HERSHEY_SIMPLEX, 0.5, (0, 255, 0), 2)
# Display the frame with tracking results
cv2.imshow('ByteTrack Surveillance', frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
Example 2: Autonomous Vehicle Tracking
This example demonstrates using ByteTrack for tracking objects in the environment of an autonomous vehicle.
# Import necessary modules
from byte_track import ByteTracker
import cv2
# Initialize the tracking model
tracker = ByteTracker()
# Load a video feed from the vehicle's camera
cap = cv2.VideoCapture('autonomous_feed.mp4')
while cap.isOpened():
ret, frame = cap.read()
if not ret:
break
# Track objects in the current frame
boxes, ids = tracker.track(frame)
for box_id in zip(boxes, ids):
x1, y1, x2, y2, id = box_id
cv2.rectangle(frame, (x1, y1), (x2, y2), (0, 255, 0), 2)
cv2.putText(frame, f'ID: {id}', (x1, y1 - 30), cv2.FONT_HERSHEY_SIMPLEX, 0.5, (0, 255, 0), 2)
# Display the frame with tracking results
cv2.imshow('Autonomous Vehicle Tracking', frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
