This project is a collaborative fog node-based fish detection system. It leverages fog computing to distribute image processing tasks across multiple clients and a server. The system is designed to detect fish in images and provide bounding box information using the Roboflow API.

• Image Upload: Users can upload an image of their choice to the application.
• Image Processing: The uploaded image is processed by a remote server using a machine learning model.
• Result Display: Processed images are displayed in the web application.
• File Management: The "received" directory is cleared before each server run.

Before running the application, make sure you have the following installed:

• Python 3.x
• Flask
• Pillow (PIL)
• tqdm
• Roboflow (for machine learning model predictions)
• A machine learning model for image processing (used in the server.py script)

1. Clone the Repository:

   • On your local machine, clone this main repository:

      git clone https://github.com/firas-chakroun/fog_computing_fish_detection.git

   • On other machines, clone the client repositories accordingly:

2. Install Dependencies:

   • Open your terminal in the project directory and install the required Python libraries using pip:

     pip install flask pillow roboflow tqdm

3. Start the Server:

   • Activate the Flask server by running the following command:

     python server/app.py

4. Access the Web Interface:

   • After the server is active, open a web browser and navigate to localhost:5000.

5. Upload an Image:

   • You can upload an image on the main page.

6. Run the Clients:

   • On the other machines, activate both client applications by running the following command on each machine:

     python client1/client.py

     python client2/client.py

7. Get Results:

   • Wait for the results to appear on the server machine. The collaborative "Fish Detection" project will process the uploaded image and display the results on the server.

If there are any problems when running server.py or client.py, try to change the socket port and don't forget to change the server's IP address in client.py.

To set up this collaborative fish detection system, follow these steps:

After creating a local network, set up the server socket to accept connections from both client nodes.

Once both clients are connected, the server splits the image into two and sends each client one-half of the image.

On the client side, the image is processed, and the results are saved with bounding boxes using the Roboflow API trained for fish detection.

The server initializes another socket to accept images from the clients after the detection process. This communication can include either sending the processed image or a JSON file containing bounding box information (in case you need to count the fish). For performance reasons, we do not perform this action.

After receiving the images and bounding boxes, install Flask and create Flask functionalities. Create a home page where users can upload an image. When an image is uploaded, the server will activate and wait for the clients to process it.

Once the processing is completed by both clients, the results are displayed

To evaluate the performance of this collaborative fish detection system, a comparison of execution times is conducted. A second server is introduced to perform fish detection in a traditional, non-distributed manner. The execution times of both servers are compared to determine the efficiency of the collaborative approach.

In conclusion, this project showcases the power of collaborative fog nodes for efficient fish detection. The collaborative approach leverages distributed processing, making it potentially faster and more efficient than traditional methods. The comparison of execution times provides insights into the system's performance.This project serves as a practical example of distributed computing for image recognition tasks.
