The paper introduces MUSTARD, a multimodal spatiotemporal anomaly detection framework that enhances large language models with fine‑grained motion awareness for industrial defect detection. It uses optical‑flow‑guided keyframe selection and augmented modalities to capture local motion patterns and global dynamic evolution, enabling detection of dynamics‑based anomalies without model updates. Experiments show that MUSTARD outperforms existing methods in identifying spatiotemporal defects and offers interpretable explanations.

The paper introduces Anomaly‑LR, a defect‑grounded latent reasoning framework for industrial anomaly detection that builds a global understanding of an image and then refines anomaly‑relevant representations directly in visual latent space. It also presents IAD‑LR‑22K, a new instruction dataset with 22,228 image‑question pairs and detailed annotations. Experiments demonstrate that Anomaly‑LR outperforms comparable‑scale methods on multiple IAD benchmarks without needing external references or tools.

This survey reviews industrial anomaly synthesis (IAS), a field that has been underrepresented in prior studies focused on anomaly detection. It categorizes IAS methods into four paradigms—hand‑crafted, distribution‑hypothesis, generative model, and vision‑language model—while presenting a taxonomy that facilitates systematic comparison. The paper also discusses datasets, benchmarks, evaluation metrics, multimodal advances, and practical deployment considerations, offering guidance for future research.
