Real-time Object Detection and Tracking with YOLOv8 and Streamlit

This repository is a comprehensive open-source project that demonstrates the integration of object detection and tracking using the YOLOv8 object detection algorithm and Streamlit, a popular Python web application framework for building interactive web applications. This project provides a user-friendly and customizable interface that can detect and track objects in real-time video streams.

Requirements

Python 3.6+ YOLOv8 Streamlit

pip install ultralytics streamlit pafy

Installation

Clone the repository: git clone https://github.com/CodingMantras/yolov8-streamlit-detection-tracking.git
Change to the repository directory: cd yolov8-streamlit-detection-tracking
Create weights, videos, and images directories inside the project.
Download the pre-trained YOLOv8 weights from (https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8n.pt) and save them to the weights directory in the same project.

Usage

Run the app with the following command: streamlit run app.py
The app should open in a new browser window.

ML Model Config

Select task (Detection, Segmentation)
Select model confidence
Use the slider to adjust the confidence threshold (25-100) for the model.

One the model config is done, select a source.

Detection on images

The default image with its objects-detected image is displayed on the main page.
Select a source. (radio button selection Image).
Upload an image by clicking on the "Browse files" button.
Click the "Detect Objects" button to run the object detection algorithm on the uploaded image with the selected confidence threshold.
The resulting image with objects detected will be displayed on the page. Click the "Download Image" button to download the image.("If save image to download" is selected)

Detection in Videos

Create a folder with name videos in the same directory
Dump your videos in this folder
In settings.py edit the following lines.

# video
VIDEO_DIR = ROOT / 'videos' # After creating the videos folder

# Suppose you have four videos inside videos folder
# Edit the name of video_1, 2, 3, 4 (with the names of your video files) 
VIDEO_1_PATH = VIDEO_DIR / 'video_1.mp4' 
VIDEO_2_PATH = VIDEO_DIR / 'video_2.mp4'
VIDEO_3_PATH = VIDEO_DIR / 'video_3.mp4'
VIDEO_4_PATH = VIDEO_DIR / 'video_4.mp4'

# Edit the same names here also.
VIDEOS_DICT = {
    'video_1': VIDEO_1_PATH,
    'video_2': VIDEO_2_PATH,
    'video_3': VIDEO_3_PATH,
    'video_4': VIDEO_4_PATH,
}

# Your videos will start appearing inside streamlit webapp 'Choose a video'.

Click on Detect Video Objects button and the selected task (detection/segmentation) will start on the selected video.

Detection on RTSP

Select the RTSP stream button
Enter the rtsp url inside the textbox and hit Detect Objects button

Detection on YouTube Video URL

Select the source as YouTube
Copy paste the url inside the text box.
The detection/segmentation task will start on the YouTube video url
