Contour-enhanced attention CNN for CT-based COVID-19 segmentation

作者:

Highlights:

• Accurate detection of COVID-19 is one of the challenging research topics in today's healthcare sector to control the coronavirus pandemic.

• The proposed Attention Decoder CNN fuses shape, boundary information from CT contours to enhance discriminability of COVID-19 infection.

• A pixel-precise attention upsampling module has been proposed to leverage encoder context towards reconstructing the high-resolution segmentation map.

• The proposed CNN displayed state-of-the-art results with a high 85.43% dice score and 88.10% recall on the combined MosMed and Jun Ma dataset.
