Abstract

As one of the most lethal infectious diseases in the world today, the prevention, control and treatment of COVID-19 have become the focus of global public health. In view of the low efficiency of manual detection methods for COVID-19 chest radiographs, and the possibility of misdiagnosis and missed diagnosis, a DA-COVID Net model for image classification of COVID-19 chest radiographs was proposed. Based on the residual network ResNet50 model, the parallel loca-tion attention module and channel attention module are introduced to enhance the feature representation, and then the classification output is performed after fusion. After pre-processing such as clipping and data enhancement, the data set was put into DA-COVID Net model for training. The experimental results show that DA-COVID Net has achieved 97.7% accuracy in the classification of COVID-19 chest radiographs, which is significantly improved compared with other models. With excellent performance evaluation indexes and fast convergence, DA-COVID Net can provide convenient and reliable basis for clinical diagnosis of COVID-19.
