MPS-Net: Multi-Point Supervised Network for CT Image Segmentation of COVID-19

Abstract: The new coronavirus, which has become a global pandemic, has confirmed more than 88 million cases worldwide since the first case was recorded in December 2019, causing over 1.9 million deaths. Since COIVD-19 lesions have clear imaging features on CT images, it is suitable for the auxiliary diagnosis and treatment of COVID-19. Deep learning can be used to segment the lesions areas of COVID-19 in CT images to help monitor the epidemic situation. In this paper, we propose a multi-point supervision network (MPS-Ne… Show more

“…The 3D transformation of these architectures and the integration into our pipeline would be an interesting experiment to evaluate improvement possibilities. Other high-performance 2D approaches like Saood et al [ 37 ] and Pei et al [ 38 ] were difficult to compare due to these models are purely trained and evaluated on 2D slices with COVID-19 presence [ 66 ].…”

“…To accurately segment COVID-19 infected regions, and to solve the problem of the diversity of lesion shapes and areas, Pei et al [ 96 ] presented an architecture referred to as the multi-point supervision network (MPS-Net). Multi-scale feature extraction and sieve connection were used to extract features of various sizes.…”
