        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()

Core Concepts

Main functionality

ByteTrack uses a combination of deep learning models and online tracking algorithms to achieve real-time object detection. The system can handle multiple objects simultaneously, making it suitable for complex scenarios.

API overview

The ByteTrack API is designed to be user-friendly, with methods like track() that allow you to integrate the tracker into your applications seamlessly.

Example Usage

Here’s a more detailed example of how to use the ByteTrack API:

# Import necessary modules
from byte_track import ByteTracker

# Initialize the tracking model
tracker = ByteTracker()

# Load an input video or frame sequence
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)

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'):
