ImprovedPneumoniaCNN: Pneumonia Detection from Chest X-rays

This repository hosts ImprovedPneumoniaCNN, a custom Convolutional Neural Network model designed to detect Pneumonia from chest X-ray images. It incorporates enhancements like dropout, batch normalization, SiLU activation, and Convolutional Block Attention Module (CBAM) for improved robustness and generalization.

How to Use

Install Dependencies

pip install torch torchvision albumentations scikit-learn matplotlib seaborn
import torch
from torchvision import transforms
from PIL import Image
from model import ImprovedPneumoniaCNN  # make sure model is defined/imported

# Load model
model = ImprovedPneumoniaCNN()
model.load_state_dict(torch.load("improved_pneumonia_cnn.pth", map_location=torch.device('cpu')))
model.eval()

# Preprocess image
transform = transforms.Compose([
    transforms.Grayscale(),
    transforms.Resize((224, 224)),
    transforms.ToTensor(),
])

img = Image.open("path_to_chest_xray.jpg")
img_tensor = transform(img).unsqueeze(0)

# Predict
with torch.no_grad():
    output = model(img_tensor)
    prediction = torch.sigmoid(output).item()
    print("Pneumonia" if prediction > 0.5 else "Normal")
