The document presents two proposed models for detecting COVID-19 from X-ray images using artificial intelligence. The first model uses deep learning with data augmentation and preprocessing of X-ray images, evaluating different optimizers and activation functions. It achieves the best accuracy of 95.2% using Adam optimizer and LeakyReLU activation. The second model performs feature fusion of GLCM and CNN features, achieving 96.1% accuracy with a batch size of 128. Previous work on COVID-19 classification using methods like SVM and deep learning are also discussed. Future work can focus on expanding datasets and interpreting model results.
