CCBlock: an effective use of deep learning for automatic diagnosis of COVID-19 using X-ray images

Abstract

Propose Troubling countries one after another, the COVID-19 pandemic has dramatically affected the health and well-being of the world’s population. The disease may continue to persist more extensively due to the increasing number of new cases daily, the rapid spread of the virus, and delay in the PCR analysis results. Therefore, it is necessary to consider developing assistive methods for detecting and diagnosing the COVID-19 to eradicate the spread of the novel coronavirus among people. Based on convolutional neural networks (CNNs), automated detection systems have shown promising results of diagnosing patients with the COVID-19 through radiography; thus, they are introduced as a workable solution to the COVID-19 diagnosis. Materials and methods Based on the enhancement of the classical visual geometry group (VGG) network with the convolutional COVID block ( CCBlock ), an efficient screening model was proposed in this study to diagnose and distinguish patients with the COVID-19 from those with pneumonia and the healthy people through radiography. The model testing dataset included 1828 X-ray images available on public platforms. Three hundred and ten images were showing confirmed COVID-19 cases, 864 images indicating pneumonia cases, and 654 images showing healthy people. Results According to the test results, enhancing the classical VGG network with radiography provided the highest diagnosis performance and overall accuracy of 98.52% for two classes as well as accuracy of 95.34% for three classes. Conclusions According to the results, using the enhanced VGG deep neural network can help radiologists automatically diagnose the COVID-19 through radiography.

Deep CNN for the Identification of Pneumonia Respiratory Disease in Chest X-Ray Imagery

“…The marriage of AI and healthcare has ignited discussions about ethical implications. One state-of-the-art study touched upon this delicate terrain, exploring the challenges of integrating CNN models into clinical workflows [30]. Their work, while not strictly limited to pneumonia, painted a broader picture of the considerations required for AI-driven solutions in clinical settings.…”

LCSB-inception: Reliable and effective light-chroma separated branches for Covid-19 detection from chest X-ray images

“…In their analysis, the proposed VGG19 [ 28 ] and DenseNET201 [ 29 ] performed well. Following a similar strategy [ 30 ], the authors presented an extension of the VGG architecture by adding a convolutional COVID block (block). The accuracy reported by the authors for the three-class categorization was 95.3%.…”
