A Few-Shot U-Net Deep Learning Model for COVID-19 Infected Area Segmentation in CT Images.

Sensors (Basel, Switzerland)

Voulodimos A, Protopapadakis E, Katsamenis I, Doulamis A, Doulamis N.
PMID: 33810066
Sensors (Basel). 2021 Mar 22;21(6). doi: 10.3390/s21062215.

Recent studies indicate that detecting radiographic patterns on CT chest scans can yield high sensitivity and specificity for COVID-19 identification. In this paper, we scrutinize the effectiveness of deep learning models for semantic segmentation of pneumonia-infected area segmentation in...
