X Ray Image Detection. Covid 19 detection from chest x ray images using deep learning and convolutional neural networks unlike other viruses covid 19 has a long incubation period ranging from 3 days to 13 days although on average the time from exposure to symptom onset is approximately five to six days. This is significant because currently no effective treatment option has been found and therefore effective diagnosis is critical.

There are a number of problems with kaggle s chest x ray dataset namely noisy incorrect labels but it served as a good enough starting point for this proof of concept covid 19 detector. I have demonstrated how to classify positive and negative pneumonia data from a collection of x ray images. To do so i used kaggle s chest x ray images pneumonia dataset and sampled 25 x ray images from healthy patients figure 2 right.
I have demonstrated how to classify positive and negative pneumonia data from a collection of x ray images.
Imaging detectors such as photographic plates and x ray film photographic film now mostly replaced by various digitizing devices like image plates or flat panel detectors and dose measurement devices such as. Using x ray images for the automated detection of covid 19 might be helpful in particular for countries and hospitals that are unable to purchase a laboratory kit for tests or that do not have a ct scanner. To this end we apply opencv s contour detection using otsu binarization and retrieve the minimum size bounding box which does not need to be axis alignedthis works sufficiently well as long as the majority of the image carrier is within the image cf. I have demonstrated how to classify positive and negative pneumonia data from a collection of x ray images.
