QiddNet: enhancing industrial quartz defect detection via unsupervised reconstruction
摘要
Industrial quartz is vital to high-end manufacturing, where accurate surface inspection helps reduce supply chain loss. We present QiddNet, an unsupervised reconstruction framework that addresses multi-scale defects and generalization to unseen anomalies. Instead of proposing a new anomaly detection paradigm, QiddNet integrates a multi-scale squeeze–excite RepViTBlock (MS-SERVB) for dynamic multi-scale defect feature capture, an adaptive residual mask self-attention (ARMSA) mechanism for focusing on defect regions, and a dynamic feature fusion-up-sampling (DF-Up) module for high-fidelity image reconstruction. Our constructed industrial quartz defect dataset (IQDD) demonstrates QiddNet’s superiority, achieving an image-level AUROC of 98.6%, a pixel-level AUROC of 94.9%, and a per-region overlap of 80.6%. Cross-domain experiments further confirmed its excellent generalization ability, with average accuracies of 99.1% and 98.7% for I-AUROC and 94.4% and 98.4% for P-AUROC on the public datasets MVTec AD and MPDD, respectively. These results highlight QiddNet’s potential to significantly improve industrial quartz defect detection accuracy and localization precision.
