摘要
Coronavirus disease 2019(Covid-19)is a life-threatening infectious disease caused by a newly discovered strain of the coronaviruses.As by the end of 2020,Covid-19 is still not fully understood,but like other similar viruses,the main mode of transmission or spread is believed to be through droplets from coughs and sneezes of infected persons.The accurate detection of Covid-19 cases poses some questions to scientists and physicians.The two main kinds of tests available for Covid-19 are viral tests,which tells you whether you are currently infected and antibody test,which tells if you had been infected previously.Rou-tine Covid-19 test can take up to 2 days to complete;in reducing chances of false negative results,serial testing is used.Medical image processing by means of using Chest X-ray images and Computed Tomography(CT)can help radiologists detect the virus.This imaging approach can detect certain characteristic changes in the lung associated with Covid-19.In this paper,a deep learning model or tech-nique based on the Convolutional Neural Network is proposed to improve the accuracy and precisely detect Covid-19 from Chest Xray scans by identifying structural abnormalities in scans or X-ray images.The entire model proposed is categorized into three stages:dataset,data pre-processing andfinal stage being training and classification.
