COVID-19 is a viral disease that was first observed in Wuhan, China in December 2019. This virus can be influenced organs, especially the lungs. The testing kit is one of the most common diagnostics tools for the virus that clinical centers are facing a shortage of due to the increase in patients. Also, X-ray and CT scan images play a crucial role for diagnosing. To the best of our knowledge, artificial intelligence-based methods have been utilized for COVID-19 diagnosis on the images.

Materials and Methods:

Hence, a Deep Neural Network model combined with a Global Feature Extractor called DNN-GFE is proposed for COVID-19 diagnosis with 1252 sick and 1229 Healthy CT scan images. The DNN-GFE model is developed to improve as an accurate diagnostics for classifying Sick and Normal persons. Also, the other classification models such as Decision tree, Random forest, and Neural net had been generated. In this paper, image normalization is used to create good quality images and improve the diagnosis of COVID-19. Furthermore, the 10-fold cross-validation technique is utilized for partitioning the data into training, testing, and validation.


The experimental results of the DNN-GFE model were compared with three classification models for COVID-19 diagnosis regarding accuracy so that the DNN-GFE model has the most accuracy of 96.71%.



The proposed model has the best performance regarding evaluation metrics over the existing models that can be utilized instead of a testing kit for COVID-19 diagnosis for clinicians.
