Abstract
The objective of this research endeavor is to identify an effective model for the classification of multiple viral respiratory diseases, encompassing COVID-19. The feature extraction phase from medical images constitutes a formidable challenge in achieving optimal disease classification outcomes. In this work, a selection of the best models among several popular transfer learning (TL) models is realized. The concatenation of the best models for better features extraction is used; the deep learning (DL) methods for deep features extraction and deep data reduction were applied for an optimal classification. This paper includes two studies, the first was applied to binary classification (COVID-19/Normal) and the second is concerned with multi-classification (COVID-19/Normal/VPneumonia). The validation of the proposed approaches is made on a big datasets: (i) binary classification 4800 COVID-19 and 4803 Normal images for the two cases Chest X-Ray (CXR) and Computed Tomography (CT) scans, and (ii) multi-class classification 3931 COVID-19, 3931 Normal, and 4273 Viral Pneumonia (VP) images for CXR. This study hypothesized that the proposed approach might be able to extract specific graphical features of COVID-19 and provide a clinical diagnosis ahead of the pathogenic test. Experimental results achieved in binary classification a high: Val_accuracy = 99.87% and 98.41%, Test_accuracy = 100% and 99.21%, Test_time = 0.002 s and 0.008 s per image for CT scans and CXR images, respectively, and in multi-classification: Val_accuracy = 97.48%, Test_accuracy = 92.96% with Test_time = 0.006 s per image for CXR images.
