Automated System for Identifying COVID-19 Infections in Computed Tomography Images Using Deep Learning Models

Abstract

Coronavirus disease 2019 (COVID-19) is a novel disease that affects healthcare on a global scale and cannot be ignored because of its high fatality rate. Computed tomography (CT) images are presently being employed to assist doctors in detecting COVID-19 in its early stages. In several scenarios, a combination of epidemiological criteria (contact during the incubation period), the existence of clinical symptoms, laboratory tests (nucleic acid amplification tests), and clinical imaging-based tests are used to diagnose COVID-19. This method can miss patients and cause more complications. Deep learning is one of the techniques that has been proven to be prominent and reliable in several diagnostic domains involving medical imaging. This study utilizes a convolutional neural network (CNN), stacked autoencoder, and deep neural network to develop a COVID-19 diagnostic system. In this system, classification undergoes some modification before applying the three CT image techniques to determine normal and COVID-19 cases. A large-scale and challenging CT image dataset was used in the training process of the employed deep learning model and reporting their final performance. Experimental outcomes show that the highest accuracy rate was achieved using the CNN model with an accuracy of 88.30%, a sensitivity of 87.65%, and a specificity of 87.97%. Furthermore, the proposed system has outperformed the current existing state-of-the-art models in detecting the COVID-19 virus using CT images.

Novel Crow Swarm Optimization Algorithm and Selection Approach for Optimal Deep Learning COVID-19 Diagnostic Model

“…It has achieved significant diagnostic outcomes in different disease detection types, including cancers and brain, heart, and lung diseases [ 44 ]. The different image-based datasets such as ImageNet introduces millions of images as training and testing dataset [ 45 ]. For instance, in 2020 [ 46 ], DL models show dermatologist-level execution on classifying skin lesions.…”

A novel deep fusion strategy for COVID-19 prediction using multimodality approach

“…Based on COVID-19 computed tomography scans, authors utilized DRL masked extraction-based approaches to capture visual characteristics of COVID-19 affected regions and deliver a precise medical assessment, all while improving the pathogenic lab test and speeding up the process. In article [16] , authors developed a COVID-19 diagnosis system using a convolutional neural network (CNN), stacked autoencoder, and deep neural network. In this approach, categorization is modified before the three CT imaging techniques are used to distinguish between normal and COVID-19 instances.…”
