Ith results shown in Table 1. The increase in accuracy is exceptionally critical when it involves the diagnosis of a significant health-related condition for instance COVID-19. The highest reported accuracy was again accomplished applying VGG16 with an average value of 94.26 , precision of 99 , recall of 99.18 , and F1-Measure of 99.09 . The lowest accuracy is again reported applying the Hexazinone MedChemExpress GoogleNet with an average value of 90.38 .Table four.

This scenario offers the most effective benefits as compared to that on the experiment shown in Table 1. As is usually observed, the enhancement of pictures increased accuracy significantly compared with those reported in Table 1, using the highest accuracy achieved by VGG19 with an average value of 94.92 , precision of 99.37 , recall of 99.28 , and F1-measure of 99.33 . The lowest accuracy is reported using the GoogleNet, with an typical worth of 89.two .Table 5.

The results are much better as in comparison with the results obtained in Table 2. Once more, we observe a rise in accuracy, with the highest reported accuracy making use of the VGG16 with an average worth of 94.98 , precision of 100 , recall of 97.63 , and F1-measure of 98.eight . The lowest accuracy is reported once again for GoogleNet, with an average value of 84.76 . Enhancement of data improved the accuracy for both normalized and non-normalized information.Table 6.

The lowest accuracy achievement continues to become for the GoogleNet with an typical value of 88.43 . These results show that using a sizable dataset, an acceptable larger degree of accuracy is accomplished applying the optimized DL models. Using a sizable dataset, they are a few of the highest accuracies reported when in comparison with these offered inside the extant literature.Table 7.
