Abstract:

Due to the limited availability of strip surface defect samples, the application of deep neural networks in strip surface detection is constrained. To solve this practical issue, a meta‐learning‐based few‐shot semantic segmentation method is proposed. A multi‐scale decoder and attention mechanism are used in the proposed method. The multi‐scale decoder can aggregate the defect information at different scales and improve segmentation accuracy of the proposed network. The attention mechanism can effectively improve the expression of defect features and suppress the interference of defect background information. In addition, a novel few‐shot steel strip surface defect semantic segmentation dataset is constructed including nine classes of strip steel surface defects. Comparison experiments on the proposed dataset show that the proposed method is superior to similar few‐shot segmentation methods such as PFENet, SCLNet, and HSNet in terms of evaluation index mean intersection over union and foreground‐background intersection over union.

Key words: strip steel surface defect detection, meta‐learning, few‐shot semantic segmentation, attention mechanism, multi‐scale decoder
