MultiBlock‐SwinUNet: A Noise‐Robust Framework for Crack Segmentation of Multi‐Class Concrete in CT Images

IET Image Processing, Volume 20, Issue 1, January/December 2026.
Existing methods often struggle to balance accuracy and robustness against complex interference such as noise and artefacts inherent in industrial CT imaging. To overcome these limitations, we propose an innovative framework named MultiBlock‐SwinUnet. This architecture is designed to enhance feature extraction for different categories of concrete and ...
