In this article, we will explore how to effectively utilize various convolutional neural network (CNN) architectures to achieve real-time fire detection without relying on temporal information. This methodology focuses on compact CNN models that maintain high accuracy while offering improved computational efficiency. Let’s dive in!
System Requirements
Before we begin, make sure your development environment meets the following prerequisites:
- Python 3.7.x
- TensorFlow 1.15
- TFLearn 0.3.2
- OpenCV 3.x or 4.x (Including additional modules for superpixel segmentation)
Understanding the Architectures
The models we’ll be working with are tailored for detecting fire within images. Here’s how they function:
Visualize the CNN models like a team of inspectors, each with a different specialty. The inspectors are tasked with identifying fire regions in images. These various models can be seen as inspectors with distinct methods for assessing the situation—some observe the entire scene at once, while others analyze specific sections (superpixels) of the image.
Core Models
- FireNet: Sees the whole image and quickly determines if fire is present.
- InceptionV1-OnFire: More refined in its approach, providing excellent results.
- InceptionV3-OnFire & InceptionV4-OnFire: Offer improved performance metrics but require additional computational resources.
- SP-Inception Models: Focus on superpixel segmentation, breaking the image into smaller sections for detailed examination.
Implementing the Models
To get started with modeling, follow these steps:
- Clone the repository from GitHub:
- Navigate to the project directory:
- Download the pre-trained models:
- Run the fire detection:
- Explore further with different models, specifying the model number with -m:
$ git clone https://github.com/tobybreckon/fire-detection-cnn.git
$ cd fire-detection-cnn
$ sh .download-models.sh
$ python firenet.py modelstest.mp4
$ python inceptionVxOnFire.py -m 1 modelstest.mp4
Choosing the Right Model
While implementing the models, it’s crucial to know which one to use:
- For the best detection performance, leverage InceptionV4-OnFire (operating at 12 fps).
- For higher throughput (17 fps), use FireNet, although it has slightly lesser accuracy.
- The SP-Inception4-OnFire model shines in localized fire detection.
Troubleshooting
If you encounter issues during installation or performance drops, consider the following:
- Ensure you are using the correct version of Python and libraries.
- Check for any missing dependencies, particularly OpenCV extra modules.
- For running the models, ensure that the downloaded pre-trained models are accessible within the expected directory.
- If facing TensorFlow compatibility issues, try setting up a virtual environment specifically for TensorFlow 1.x.
