COVID-XNet: A Custom Deep Learning System to Diagnose and Locate COVID-19 in Chest X-ray Images

Abstract: The COVID-19 pandemic caused by the new coronavirus SARS-CoV-2 has changed the world as we know it. An early diagnosis is crucial in order to prevent new outbreaks and control its rapid spread. Medical imaging techniques, such as X-ray or chest computed tomography, are commonly used for this purpose due to their reliability for COVID-19 diagnosis. Computer-aided diagnosis systems could play an essential role in aiding radiologists in the screening process. In this work, a novel Deep Learning-based system, call… Show more

“…reduced false negative rates) along with other metrics. Our proposed CNN model shows better specificity (97.01%) than many existing works (Abbas et al, 2020; Apostolopoulos & Mpesiana, 2020; Minaee et al, 2020; Chandra et al, 2021; Duran-Lopez et al, 2020; Pandit & Banday, 2020). At the application level, the usage of our model may prevent COVID-19 community transmission by detecting false negative cases more accurately.…”

“…Moura et al (2020) investigated 1616 chest X-ray images using DenseNet161 where it shows 79.89% accuracy to classify normal, pathological and COVID-19 patients. Duran-Lopez et al (2020) represented a custom CNN based model named COVID-XNet that shows 94.43% average accuracy, 98.8% AUC, 96.33% sensitivity, and 93.76% specificity respectively. Shorfuzzaman & Hossain (2020) provided a siamese neural network called MetaCOVID to integrate contrastive learning with a fine-tuned pre-trained ConvNet encoder and capture unbiased feature representations using 10-shot learning scores and compared among the meta learning algorithm with InceptionV3, Xception, Inception, ResNetV2, and VGG16.…”

“…There have been multiple works done by researchers in the area of COVID-19 patient detection using CXR images [4,5,7,12,[26][27][28][29][30][31][32]. In one such work by Makris et al [4], transfer learning has been used with the Inception-v3 network to classify normal, pneumonia and COVID-19 patients using CXR images.…”

“…Clearly, the application of these technologies in the field of e-Health, both in the analysis of physiological signals and as diagnostic aid systems with medical images, has an enormous impact and helps to significantly reduce the workload of healthcare professionals. Several works related to this area can be found [ 25 , 26 , 27 , 28 ], and currently we can even find some interesting applications related to the detection of COVID-19 [ 29 , 30 ]. Due to the rise of these systems, it is interesting to carry out a preliminary dataset study using DL techniques in order to evaluate its quality.…”
