With the development of artificial intelligence (AI), there have been some studies on automated TEM virus identification using deep learning. However, to achieve effective virus identification results, a large number of high-quality labeled images are required for network training. In this work, we propose an automatic virus segmentation method based on few-shot learning. We use the Chikungunya virus, Parapoxvirus and Marburg virus, etc. to construct a pre-training virus dataset and train an attention U-Net-like network with an encoder module, relationship module, attention module and decoding module to realize severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) segmentation using few-shot learning. The experiment shows that the proposed few-shot learning methods yield 0.900 Dice and 0.828 Jaccard in 1-shot, 0.903 Dice and 0.832 Jaccard in 5-shot, which demonstrates the effectiveness of our method and outperforms other promising methods. Our fully automated method contributes to the development of medical virology by providing virologists with a low-cost and accurate approach to identify SARS-CoV-2 in TEM. <\/jats:p>","DOI":"10.1142\/s0219691323500479","type":"journal-article","created":{"date-parts":[[2023,9,16]],"date-time":"2023-09-16T05:03:00Z","timestamp":1694840580000},"source":"Crossref","is-referenced-by-count":1,"title":["Automatic SARS-CoV-2 segmentation in electron microscopy based on few-shot learning"],"prefix":"10.1142","volume":"22","author":[{"given":"Chi","family":"Xiao","sequence":"first","affiliation":[{"name":"Key Laboratory of Biomedical Engineering of Hainan Province, School of Biomedical Engineering, Hainan University, Haikou 570228, P.
