Author links open overlay panel nafaa nacereddine a aicha baya goumeidane a djemel ziou b. Early screening of sars-cov-2 by intelligent analysis of x-ray images. Future sars-cov-2 virus outbreak covid-xx might possibly occur during the next years. Figure 1 examples of chest ct images of covid-19 () patients and visualization of features correlated to covid-19 positivity. For each pair of images, the left image is a ct image showing the segmented lung used as input for the cnn (convolutional neural network algorithm) model trained on ct images only, and the right image shows the heatmap of pixels that the cnn model classified as having.
