- Abstract: COVID19 is a highly contagious disease infected millions of people worldwide.
With limited testing components, screening tools such as chest radiography can
assist the clinicians in the diagnosis and assessing the progress of disease.
The performance of deep learning-based systems for diagnosis of COVID-19
disease in radiograph images has been encouraging. This paper investigates the
concept of transfer learning using two of the most well-known VGGNet
architectures, namely VGG-16 and VGG-19. The classifier block and
hyperparameters are fine-tuned to adopt the models for automatic detection of
Covid-19 in chest x-ray images. We generated two different datasets to evaluate
the performance of the proposed system for the identification of positive
Covid-19 instances in a multiclass and binary classification problems. The
experimental outcome demonstrates the usefulness of transfer learning for
small-sized datasets particularly in the field of medical imaging, not only to
prevent over-fitting and convergence problems but also to attain optimal
classification performance as well.
