Artificial Intelligence Framework for Efficient Detection and Classification of Pneumonia Using Chest Radiography Images

Abstract: BackgroundChest diseases are serious health problems that threaten the lives of people. The early and accurate diagnosis of such diseases is very crucial in the success of their treatment and cure. Pneumonia is one of the most widely occurred chest diseases responsible for a high percentage of deaths especially among children. So, detection and classification of pneumonia using the non-invasive chest x-ray imaging would have a great advantage of reducing the mortality rates.ResultsThe results showed that the b… Show more

“…It is clear from the table that PneumoniaNet outperforms all other models with respect to all important performance metrics. The new model accuracy is the highest, with 99.72% accuracy, a 5% increase from the second-best model accuracy of 94.03% reported by Alqudah et al in 2021 [16]. Because the accuracy metric by itself can be misleading, other performance metrics of interest such as the new model sensitivity, specificity, precision, and AUC are reported, and they are also better than what is described in the literature.…”

“…Sensitivity is the most important metric in medical applications because it shows the percentage of correct positives, and Table 3 shows that the proposed model recall is 99.74%. It is also clear in Table 3 that all previous work [13][14][15][16][17] achieved lower accuracy, sensitivity, precision, and F1 when compared with the suggested method. On top of that, their dataset size is smaller than the one used in this paper.…”

“…Pre-trained networks are trained on an Imagenet database [ 40 ] consisting of 1000 image classes. Even though trained on non-biomedical images, pre-trained CNNs in combination with off-the-shelf classifiers were found successful in the detection of a wide range of diseases from X-ray images, including tuberculosis [ 41 ], breast cancer [ 42 ] and pneumonia [ 43 ]. The convolutional layers built on top of each other, learn more complex features for reliable classification tasks.…”
