🔥 Real-Time Fire Detection System

📌 Project Overview

This project implements a deep learning-based fire detection system using the MobileNet architecture. The model is designed to identify fire in images or video frames in real time, enabling early detection and faster response to potential hazards.

The solution leverages lightweight convolutional neural networks to ensure efficient performance, making it suitable for deployment on resource-constrained devices such as edge systems and mobile platforms.

🎯 Problem Statement

Fire accidents cause significant loss to life, property, and the environment. Traditional fire detection systems rely on sensors (smoke/temperature), which often:

  • Detect fire at a later stage
  • Fail in open or large environments
  • Lack visual confirmation

This project addresses these limitations using computer vision and deep learning for early visual fire detection.

🚀 Objectives

  • Build a fire detection model using MobileNet
  • Classify images into Fire / No Fire
  • Enable real-time detection using video/webcam
  • Optimize model for fast inference and low resource usage

🧠 Model & Approach

🔹 Why MobileNet?

  • Lightweight and efficient CNN architecture
  • Uses depthwise separable convolutions
  • Suitable for real-time and edge deployment

MobileNet-based systems are widely used for fire detection due to their efficiency and ability to run on low-power devices while maintaining high accuracy :contentReference[oaicite:0]{index=0}.

🔹 Workflow

  1. Data Collection (Fire & Non-Fire images)
  2. Data Preprocessing (Resizing, normalization)
  3. Model Training using MobileNet
  4. Evaluation (Accuracy, loss)
  5. Inference on images / video

🛠️ Tech Stack

  • Python – Core programming
  • TensorFlow / Keras – Model building
  • OpenCV – Image & video processing
  • NumPy & Pandas – Data handling
  • Matplotlib – Visualization
