FreqPrompt-AD: Frequency-guided local semantic prompting for zero-shot industrial anomaly detection and segmentation

Zero-shot industrial anomaly detection aims to identify and segment defects in unseen categories without target-specific model fitting. CLIP-style vision-language models (VLMs) provide useful semantic transferability, but their global image-text alignment often emphasizes object-level semantics and weakens the response...
