Beyond RGB: out-of-distribution detection for hyperspectral material recognition

Hyperspectral imaging (HSI) extends conventional RGB imaging by measuring light in tens to hundreds of narrow spectral bands, often extending into the short-wave infrared. The resulting wavelength-dependent responses provide information about material properties and chemical composition, enabling material recognition b...

Unified Multi-Layer Subspace Modeling for Cross-Domain OOD Detection

PRISM (Projected Representation with Intermediate-layer Subspace Modeling), a model-agnostic post-hoc OOD detection method that models a unified multi-layer feature representation rather than aggregating independently scored layers, achieves consistent state-of-the-art cross-domain OOD detection performance with a sing...

STEP: Score-Based Temporal Energy for Human Pose Video Anomaly Detection

STEP, a simple framework that utilizes Principal Component Analysis (PCA) to project pose sequences into a compact, whitened PC-space, outperforms the previous skeleton-based state-of-the-art by 12.2% on the challenging UBnormal dataset and achieves highly competitive results by improving on the ShanghaiTech benchmark.
