Abstract:

To address challenges such as weak defect features, blurred boundaries, and significant scale variations, an edge and semantic-aware segmentation network for defect detection (ESNet) was proposed. Specifically, a dual-branch network was employed to learn semantic and detailed information of the image separately. To effectively utilize the complementary information from both branches, a bilateral attention guidance module (BAGM) was proposed. This module guided the detailed branch to learn contextual information via the channel attention of the semantic branch, while the spatial attention of the detailed branch guided the semantic branch to capture low-level detailed information. In the semantic branch, a multi-scale pyramid pooling module (MPPM) was designed to thoroughly learn and encode multi-level contextual information. Simultaneously, in the detailed branch, an edge-aware module (EAM) was incorporated, which used the boundary map predicted by the lower layers to guide the higher-level feature maps in learning boundary information. Finally, to effectively fuse high-level and low-level feature maps, a semantic-aware module (SAM) was proposed to alleviate the semantic misalignment problem in cross-scale feature fusion. Extensive experiments on public defect segmentation datasets NEU-Seg, MT-Defect, and MSD demonstrated the effectiveness of the proposed method.
