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  ,  , the Radiopaedia  , Italian Society of Radiology (SIRM)  , Figshare data repository websites  ,  . Then, 912 augmented images were also collected from Mendeley instead of using data augmentation techniques explicitly  . Finally, 2313 samples of normal and pneumonia cases were obtained from Kaggle  ,  . A total of 6939 samples were used in the experiment, where 2313 samples were used for each case.
