Back to Point: Exploring Point-Language Models for Zero-Shot 3D Anomaly Detection

CVPR 2026

Zero-shot (ZS) 3D anomaly detection is crucial for reliable industrial inspection, as it enables detecting and localizing defects without requiring any target-category training data. Existing approaches render 3D point clouds into 2D images and leverage pre-trained Vision-Language Models (VLMs) for

STAD: Joint Spatial-Temporal Dimension and Channel Correlation for Time Series Anomaly Detection

ICASSP 2025accepted

Accurately identifying real anomalies and pseudo-anomalies in complex multi-dimensional time series data has been a difficult problem in time series anomaly detection. To solve this problem, this paper proposes a new framework, STAD, that joint temporal and spatial dimensions. This framework guides…

PDT Uav Target Detection Dataset for Pests and Diseases Tree

ECCV 2024poster

"UAVs emerge as the optimal carriers for visual weed identification and integrated pest and disease management in crops. However, the absence of specialized datasets impedes the advancement of model development in this domain. To address this, we have developed the Pests and Diseases Tree dataset (P…
