Creating customized web apps to improve user experience

Now, it’s time to complete our Covid-19 Detection Tool web application. So far, we have implemented several features, such as Image Enhancement and Disclaimer and Info, but we are still missing the Diagnosis section. Figure 10.1 shows what we have completed so far:

As I mentioned in Chapter 9, the task of Diagnosis is to understand from a picture, specifically from an X-ray of the chest, whether or not a patient has Covid-19.

This kind of prediction can be performed using a pretrained AI model, which in our case is a convolutional neural network (CNN). A CNN is a neural network with a peculiar structure or shape that performs very well regarding tasks related to computer vision. Computer vision, in a few words, means to make computers understand what’s going on with a picture, its content, the objects represented...
