Welcome to the Ultralytics YOLO26 🚀 notebook! <a href="https://github.com/ultralytics/ultralytics">YOLO26</a> is the latest version of the YOLO (You Only Look Once) AI models developed by <a href="https://ultralytics.com">Ultralytics</a>. This notebook serves as the starting point for exploring the various resources available to help you get started with YOLO26 and understand its features and capabilities.

YOLO26 models are fast, accurate, and easy to use, making them ideal for various object detection and image segmentation tasks. They can be trained on large datasets and run on diverse hardware platforms, from CPUs to GPUs.

We hope that the resources in this notebook will help you get the most out of YOLO26. Please browse the YOLO26 <a href="https://docs.ultralytics.com/modes/track/"> Tracking Docs</a> for details, raise an issue on <a href="https://github.com/ultralytics/ultralytics">GitHub</a> for support, and join our <a href="https://ultralytics.com/discord">Discord</a> community for questions and discussions!

ultralytics.checks()

Ultralytics Object Tracking

Ultralytics YOLO11 instance segmentation involves identifying and outlining individual objects in an image, providing a detailed understanding of spatial distribution. Unlike semantic segmentation, it uniquely labels and precisely delineates each object, crucial for tasks like object detection and medical imaging.

There are two types of instance segmentation tracking available in the Ultralytics package:

Instance Segmentation with Class Objects: Each class object is assigned a unique color for clear visual separation.
Instance Segmentation with Object Tracks: Every track is represented by a distinct color, facilitating easy identification and tracking.

Python

Python Instance Segmentation and Object tracking example.

python

from collections import defaultdict

import cv2

from ultralytics import YOLO

# Dictionary to store tracking history with default empty lists
track_history = defaultdict(lambda: [])

# Load the YOLO model with segmentation capabilities
model = YOLO("yolo26n-seg.pt")

# Open the video file
cap = cv2.VideoCapture("path/to/video.mp4")

# Retrieve video properties: width, height, and frames per second
w, h, fps = (int(cap.get(x)) for x in (cv2.CAP_PROP_FRAME_WIDTH, cv2.CAP_PROP_FRAME_HEIGHT, cv2.CAP_PROP_FPS))

# Initialize video writer to save the output video with the specified properties
out = cv2.VideoWriter("instance-segmentation-object-tracking.avi", cv2.VideoWriter_fourcc(*"MJPG"), fps, (w, h))

while True:
    # Read a frame from the video
    ret, im0 = cap.read()
    if not ret:
        print("Video frame is empty or video processing has been successfully completed.")
        break

    # Perform object tracking on the current frame
    results = model.track(im0, persist=True)

    # Plot results with instance-colored masks (each track_id gets a unique color)
    im0 = results[0].plot(color_mode="instance", line_width=2)

    # Write the annotated frame to the output video
    out.write(im0)
    # Display the annotated frame
    cv2.imshow("instance-segmentation-object-tracking", im0)

    # Exit the loop if 'q' is pressed
    if cv2.waitKey(1) & 0xFF == ord("q"):
        break

# Release the video writer and capture objects, and close all OpenCV windows
out.release()
cap.release()
cv2.destroyAllWindows()
