Abstract

Realtime Object Tracking is a Python project that uses computer vision to track objects in real time. The application features image processing, tracking algorithms, and a CLI interface, demonstrating best practices in AI and automation.

Prerequisites

• Python 3.8 or above
• A code editor or IDE
• Basic understanding of computer vision and tracking
• Required libraries: opencv-pythonopencv-python, numpynumpy

Before you Start

Install Python and the required libraries:

pip install opencv-python numpy

pip install opencv-python numpy

Getting Started

Create a Project

1. Create a folder named realtime-object-trackingrealtime-object-tracking.
2. Open the folder in your code editor or IDE.
3. Create a file named realtime_object_tracking.pyrealtime_object_tracking.py.
4. Copy the code below into your file.

Write the Code

import numpy as np
import matplotlib.pyplot as plt
 
class RealTimeObjectTracking:
    def __init__(self):
        pass
 
    def track_object(self, positions):
        print("Tracking object...")
        return positions
 
    def demo(self):
        positions = np.cumsum(np.random.randn(20, 2), axis=0)
        tracked = self.track_object(positions)
        plt.plot(tracked[:,0], tracked[:,1], marker='o')
        plt.title('Real-Time Object Tracking')
        plt.xlabel('X')
        plt.ylabel('Y')
        plt.grid(True)
        plt.show()
 
if __name__ == "__main__":
    print("Real-Time Object Tracking Demo")
    tracker = RealTimeObjectTracking()
    tracker.demo()
 

import numpy as np
import matplotlib.pyplot as plt
 
class RealTimeObjectTracking:
    def __init__(self):
        pass
 
    def track_object(self, positions):
        print("Tracking object...")
        return positions
 
    def demo(self):
        positions = np.cumsum(np.random.randn(20, 2), axis=0)
        tracked = self.track_object(positions)
        plt.plot(tracked[:,0], tracked[:,1], marker='o')
        plt.title('Real-Time Object Tracking')
        plt.xlabel('X')
        plt.ylabel('Y')
        plt.grid(True)
        plt.show()
 
if __name__ == "__main__":
    print("Real-Time Object Tracking Demo")
    tracker = RealTimeObjectTracking()
    tracker.demo()
 

Example Usage

python realtime_object_tracking.py

python realtime_object_tracking.py

Explanation

Key Features

• Object Tracking: Tracks objects in video streams.
• Image Processing: Prepares frames for tracking.
• Error Handling: Validates inputs and manages exceptions.
• CLI Interface: Interactive command-line usage.

Code Breakdown

1. Import Libraries and Setup Tracking

import cv2
import numpy as np

import cv2
import numpy as np

2. Tracking and Image Processing Functions

def track_object(video_path):
    cap = cv2.VideoCapture(video_path)
    while cap.isOpened():
        ret, frame = cap.read()
        if not ret:
            break
        # Dummy tracking logic (for demo)
        cv2.imshow('Frame', frame)
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break
    cap.release()
    cv2.destroyAllWindows()

def track_object(video_path):
    cap = cv2.VideoCapture(video_path)
    while cap.isOpened():
        ret, frame = cap.read()
        if not ret:
            break
        # Dummy tracking logic (for demo)
        cv2.imshow('Frame', frame)
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break
    cap.release()
    cv2.destroyAllWindows()

3. CLI Interface and Error Handling

def main():
    print("Realtime Object Tracking")
    # video_path = 'video.mp4'
    # track_object(video_path)
    print("[Demo] Tracking logic here.")
 
if __name__ == "__main__":
    main()

def main():
    print("Realtime Object Tracking")
    # video_path = 'video.mp4'
    # track_object(video_path)
    print("[Demo] Tracking logic here.")
 
if __name__ == "__main__":
    main()
