However, COVID-19 being a novel disease, there is no annotated large-scale CXR dataset for this particular disease. To address the issue of limited data, we propose to exploit a large-scale CXR dataset collected in the pre-COVID era and train a deep neural network in a self-supervised ...
At the central server, we adapted the FedAvg33 algorithm to aggregate the updated model parameters from all clients (UCADI participants) to combine the weights with respect to clients’s dataset sizes and the number of local training epochs between consecutive communications. To ensure secure transmi...
performance of 315 deep models in diagnosing COVID-19, normal, and pneumonia from X-ray images of a custom dataset created from four others. The dataset is publicly available athttps://github.com/rgbnihal2/COVID-19-X-ray-Dataset. Our results show that DenseNet201 model with Quadratic SVM ...
2. Dataset collection and processing 2.1. Public data repositories To improve the classification accuracy and generalization ability of DL models for COVID-19 diagnosis, we collect CXR images as much as possible and apply data augmentation to increase the data diversity. In this research, the emplo...
Alpha diversity (a) and Unweighted Unifrac Beta diversity (b) were analysed on the basis of the dataset normalized to 105,851 reads per sample. The two groups compared were defined by SARS-CoV-2 positive infection. The differences between groups were assessed by Wilcoxon nonparametric test ...
Numerous works have been reported on COVID-19 detection from a smaller set of original X-ray images. However, the effect of image enhancement and lung segmentation of a large dataset in COVID-19 detection was not reported in the literature. We have compiled a large X-ray dataset (COVQU)...
COVID-19 RADIOGRAPHY DATABASE (Winner of the COVID-19 Dataset Award by Kaggle Community) A team of researchers from Qatar University, Doha, Qatar, and the University of Dhaka, Bangladesh along with their collaborators from Pakistan and Malaysia in collaboration with medical doctors have created a...
3.5. Dataset We used three separate open sources to acquire chest X-ray data of different pneumonia-related illnesses for this investigation [52,53,54]. As described in Table 1, we acquired 3616 scans of COVID-19 CXR from the COVID-19 radiography database [52]. We acquired 3029 scans ...
In particular, his research is based on three public databases of COVID-19 chest X-rays: (1) COVID-19 Radiography Database [19], (2) COVID-19 Chest X-ray Dataset Initiative [20], and (3) IEEE8023/Covid Chest X-ray Dataset [21]. The first database [18,19] reports both positiv...
