Notes: 1) In this section we are going to do the same steps as in section 1; 2) In the download section you can get all the files that I will mention below, or you can do click here: https://github.com/guillengap/covid-19-opencv ; and 3) Once downloaded, we will use the files shown in the folder: Virus-Cells
