RAUDI: A Dual-Head Framework Unifying Unsupervised and Supervised Reconstruction for Industrial Anomaly Detection

The paper proposes RAUDI, a dual-head framework for industrial anomaly detection that unifies unsupervised and supervised learning by flexibly utilizing real defective samples or realistic pseudo-anomalies synthesized via a novel multi-stage superpixel method (RASMS), achieving state-of-the-art performance on both MVTec AD and KolektorSDD2 benchmarks.

Generalising Hybrid OUR-Net -U-Net for Accurate Identification and Multi-Domain Structural Crack Segmentation Using Refinement Techniques

This paper proposes a weakly supervised framework that leverages image-level annotations to generate refined pseudo-masks via CAM and Grad-CAM, which are then used to train a hybrid OUR-Net–U-Net model for accurate, multi-domain structural crack segmentation with significantly reduced annotation costs and superior performance compared to existing methods.

Defect-Aware YOLOv8n for Real-Time Surface Defect Detection on Printed Playing Cards with Dense Graphic Backgrounds

This paper proposes a defect-aware YOLOv8n framework enhanced with a ResNet50 backbone, DeCA, improved BiFPN with SPD-Conv, a dynamic adaptive decoupled head, and Wise-IoU v3 to achieve real-time, high-accuracy detection of small, low-contrast defects on printed playing cards amidst dense graphic backgrounds, outperforming the standard YOLOv8n by 12.8% in mAP@50 while maintaining a 97 FPS inference speed.

Prototype-aware Channel-Selective Spatial Interaction for Semi-supervised Medical Image Segmentation

This paper proposes Prototype-aware Channel-Selective Spatial Interaction (PCSI), a teacher-student framework for semi-supervised medical image segmentation that leverages decoupled foreground-background prototype memories to guide channel selection and spatial feature refinement, thereby achieving superior performance with limited labeled data.

Semantic Spectrum: Fault Localization via Method Behavioral Divergence

This paper proposes Semantic Spectrum-based Fault Localization (SSFL), a method-level approach that leverages runtime output-value distributions to construct semantic spectra, achieving superior fault localization accuracy compared to traditional spectrum-based, learning-based, and LLM-based techniques without requiring model training or online reasoning.
