COVSeg‐NET: A deep convolution neural network for COVID‐19 lung CT image segmentation

COVID-19 is a new type of respiratory infectious disease. It broke out for the first time in November 2019 and quickly swept the world in less than a year, posing a serious threat to world development and human survival. It is the most challenging problem facing the world today. The disease is caused by severe acute respiratory syndrome coronavirus 2 (SARS-COV-2), which has caused high incidence rate and mortality worldwide.1 At present, the main clinical tool for the diagnosis of COVID-19 is reverse transcription polymerase chain reaction (RT-PCR), but the detection reagent is expensive and insufficient in quantity, and it needs specialized medical personnel to use it.2
