COVID19, Pneumonia and Normal Chest X-ray PA Dataset

The dataset is organized into 3 folders (covid, pneumonia , normal) which contain chest X-ray posteroanterior (PA) images. X-ray samples of COVID-19 were retrieved from different sources for the unavailability of a large specific dataset. Firstly, a total 1401 samples of COVID-19 were collected using GitHub repository [1] , [2] , the Radiopaedia [3] , Italian Society of Radiology (SIRM) [4] , Figshare data repository websites [5] , [6] . Then, 912 augmented images were also collected from Mendeley instead of using data augmentation techniques explicitly [7] . Finally, 2313 samples of normal and pneumonia cases were obtained from Kaggle [8] , [9] . A total of 6939 samples were used in the experiment, where 2313 samples were used for each case.
