Currently, coronavirus disease 2019 (COVID-19) has not been contained. It is a safe and effective way to detect infected persons in chest X-ray (CXR) images based on deep learning methods. To solve the above problem, the dual-path multi-scale fusion (DMFF) module and dense dilated depth-wise separable (D3S) module are used to extract shallow and deep features, respectively. Based on these two modules and multi-scale spatial attention (MSA) mechanism, a lightweight convolutional neural network model, MSA-DDCovidNet, is designed. Experimental results show that the accuracy of the MSA-DDCovidNet model on COVID-19 CXR images is as high as 97.962%, In addition, the proposed MSA-DDCovidNet has less computation complexity and fewer parameter numbers. Compared with other methods, MSA-DDCovidNet can help diagnose COVID-19 more quickly and accurately.
目前，2019冠状病毒病（COVID-19）尚未得到控制。基于深度学习方法在胸部X光（CXR）图像中检测感染者是一种安全有效的方法。为了解决上述问题，分别使用双路径多尺度融合（DMFF）模块和密集扩张深度可分离（D3S）模块来提取浅层和深层特征。基于这两个模块和多尺度空间注意力（MSA）机制，设计了一种轻量级卷积神经网络模型MSA-DDCovidNet。实验结果表明，MSA-DDCovidNet模型在COVID-19 CXR图像上的准确率高达97.962%，此外，所提出的MSA-DDCovidNet具有较低的计算复杂度和较少的参数数量。与其他方法相比，MSA-DDCovidNet可以帮助更快、更准确地诊断COVID-19。
