🔬 XRay-Pneumonia-Detection-GUI

⚠️ To download the pretrained model, please refer to the Usage Section for detailed instructions.

Overview

XRay-Pneumonia-Detection-GUI is an deep learning project designed to automate pneumonia detection in X-ray images. By utilizing Convolutional Neural Networks (CNNs), this project classifies X-ray images into 'Normal' and 'Pneumonia' categories. The 'Pneumonia' class includes both bacterial and viral pneumonia cases, making it a binary classification task.

To enhance user experience and accessibility, a user-friendly GUI has been developed using Python and Kivy. This graphical interface empowers medical professionals to effortlessly upload X-ray images and obtain rapid and (often 😄) reliable results, simplifying the pneumonia diagnosis process for you.

📃 Examples

Take a look at this GIF demonstration to get a brief overview of how to use the app:

🚀 Model Description

✅ Here, you'll find essential information.

🔍 For a more detailed insight into the model and its performance, you can refer to the notebook itself. It contains comprehensive documentation and analysis of the model's architecture, training process, evaluation metrics, and visualization of results.

1. Model Architecture

This model is a deep convolutional neural network (CNN) designed for classifying X-ray images into two classes: NORMAL and PNEUMONIA. The model architecture consists of several convolutional layers, followed by max-pooling layers to extract meaningful features from the input images. The key components of the model architecture are as follows:

1. Input Layer: The model takes grayscale X-ray images as input with a shape of (300, 400).

2. Convolutional Layers: The model contains multiple convolutional layers, each with a different number of filters and kernel sizes. The activation function used in the convolutional layers is ReLU (Rectified Linear Unit), which introduces non-linearity into the model.

3. Max-Pooling Layers: After each convolutional layer, there is a max-pooling layer that reduces the spatial dimensions of the feature maps, aiding in faster computation and reducing overfitting.

4. Flatten Layer: The final max-pooled output is flattened into a 1-dimensional vector to be fed into the dense layers.

5. Dense Layers: There are two dense layers in the model. The first dense layer consists of 512 neurons with a ReLU activation function, followed by another dense layer with 2 neurons using the softmax activation function. The final layer with 2 neurons produces the probability distribution for the two classes, "NORMAL" and "PNEUMONIA."

2. Model Training

The model is trained using the available data split into training, testing, and validation sets. Data augmentation techniques, such as horizontal flipping, can be applied to the training data to increase the model's ability to generalize.

3. Model Evaluation

The model's performance is evaluated on the training, testing, and validation datasets using the evaluation metrics of loss and accuracy. Additionally, a confusion matrix is constructed to visualize the model's predictions against the true labels of the test data.

The model's performance on the dataset is as follows:

Train-loss:         0.13
Train-accuracy:     0.95

Test-loss:          0.45
Test-accuracy:      0.83

Val-loss:           0.15
Val-accuracy:       0.93

Based on the observed graph and confusion matrix, the model exhibits superior performance in predicting the PNEUMONIA class (94%) compared to the NORMAL class (72.2%). However, it is important to note that the model's performance is subject to potential improvements in the future, and further optimization may lead to enhanced accuracy and generalization capabilities.

⚠️ Please be aware that we are currently working on this project, and there are plans to make further upgrades and improvements in the future.

Kivy assets ➕

Inside the XRay-Pneumonia-Detection-App/ directory, there is an assets directory where you will store:

• The design.kv file for application's design
• The model file used to classify images
• A few images required for application, such as the intro image.

⚠️ The default model name is set to "model-2". If you decide to change it, remember to also update the "model_path" option in the configuration file accordingly.

📃 Code Description:

This is a Python script using the Kivy and KivyMD libraries to create a Graphical User Interface (GUI) for detecting pneumonia in X-ray images using a trained TensorFlow model. Let's go through the code and explain its functionality.

Imports 📦

The script starts by importing the necessary modules from various libraries, including Kivy, KivyMD, and other standard Python modules like threading, json, os, etc.

Load KV File 📃

The Builder.load_file() command is used to load the Kivy Language file (KV) that defines the GUI layout and design.

Configuration File 🔧

The script uses a JSON configuration file (config.json) to set various parameters and paths for the application, such as the model file path, window size, window theme, etc. The load_config() method reads and extracts these values from the config file.

Layout Classes 🎨

The script defines three classes for different layouts (DropFileLayout, LoadingLayout, and ModelInfoLayout) used in the application. These classes define the structure of the GUI elements.

Main Application Class - PneumoniaDetectionApp 💻

The PneumoniaDetectionApp class is the main application class that inherits from MDApp (a class from KivyMD library for creating Material Design applications).

Initialization and Building 🏗️

The build() method initializes and builds the main application. It sets the window theme based on the configuration file, shows the loading layout while the background loading takes place, and initializes the main layout (DropFileLayout).

Background Loading ⏳

The backgroundLoading() method runs in the background to import necessary modules (cv2, numpy, tensorflow, matplotlib) and loads the trained TensorFlow model. Once the loading is complete, it schedules the main layout to be displayed using Clock.schedule_once().

Reason:

While starting the Kivy window, non-essential for initiating kivy window, second-degree modules will be loaded in the background, allowing the Loading Window to be displayed. Without this background loading, the Kivy window would be created, but its content would remain frozen and not properly visualized until all the required modules are imported.

Event Handling ✋

• The on_file_selected() method is called when an image is dropped onto the application. It updates the selected image and calls analyzeImage() to analyze the image using the loaded model.
• The analyzeImage() method preprocesses the selected image and feeds it to the model for classification. It then updates the GUI with the analysis results.
• The btnModelInfo() method shows the model information layout when the "Model Info" button is pressed.
• The btnReturnMainWindow() method returns to the main window from the model information layout.
• The btnAnalyzeAgain() method allows re-analyzing the same image after modifications.
• The btnExportResults() method exports the analyzed image with the classification results.

Image Exporting 💾

The exportPNG() method draws text data on the analyzed image and exports it with the classification results.

Entry Point 🏁

The if __name__ == "__main__": block is the entry point of the script. It creates an instance of PneumoniaDetectionApp and runs the Kivy application using kivy_app.run().

Additional Note 📝

The script attempts to remove the exported image file (if any) after the Kivy application is closed.
