🚀 Motion Detection Using OpenCV and Java Swing

A Java-based real-time motion detection application that integrates OpenCV for video processing and Swing for the graphical user interface (GUI).

📋 Project Overview

This project captures video from a webcam, detects motion in real-time, and identifies the direction of motion (Left, Center, or Right). It uses OpenCV for image processing and Java Swing for the user interface.

🛠️ Features

• 📷 Real-time video capture using OpenCV.
• ⚡ Efficient motion detection using frame difference.
• 🧭 Motion direction detection: Left, Center, or Right.
• 🖥️ GUI integration for video display and feedback.
• 🎯 Visual feedback with bounding rectangles on moving objects.

🔧 How It Works

1. GUI Setup: A user-friendly interface with video display, direction feedback, and control buttons.
2. Camera Initialization: Captures video frames using OpenCV's VideoCapture.
3. Motion Detection Algorithm:
   • Grayscale conversion and Gaussian blur to reduce noise.
   • Frame difference to highlight motion areas.
   • Thresholding and dilation to clean up the motion regions.
   • Contour detection to identify motion regions.
   • Calculation of motion direction based on region centroid.
4. Visual Feedback: Bounding rectangles on motion areas and direction indication (Left, Center, Right).
5. Camera Control: Start and stop camera functionality.

💻 Technologies Used

• Java (Swing for GUI)
• OpenCV (for video processing)

🚀 How to Run

1. Install OpenCV and configure it with your Java project.
2. Ensure you have a working webcam connected to your system.
3. Run the Main.java file.

📄 Code Overview

Main.java
- createGUI(): Sets up the GUI components.
- startCamera(): Initializes the camera and starts the motion detection thread.
- stopCamera(): Releases the camera resources.
- matToBufferedImage(): Converts OpenCV Mat objects to BufferedImage for display.
- Motion Detection Logic:
    - Frame difference, thresholding, contour detection, and centroid-based direction determination.
