From Coarse to Fine: Deep Prototype Refinement Network for Few-Shot Point Cloud Semantic Segmentation

ICML 2026poster

Few-shot point cloud semantic segmentation (FS-PCSS) aims to achieve precise segmentation of novel categories using only limited labeled samples. Existing prototype-based methods typically rely on shallow feature fusion strategies, failing to adequately model the feature distribution shift between s…

FlexUOD: The Answer to Real-world Unsupervised Image Outlier Detection

CVPR 2025poster

How many outliers are within an unlabeled and contaminated dataset? Despite a series of unsupervised outlier detection (UOD) approaches have been proposed, they cannot correctly answer this critical question, resulting in their performance instability across various real-world (varying contamination…

Point Clouds Meets Physics: Dynamic Acoustic Field Fitting Network for Point Cloud Understanding

CVPR 2025poster

While existing pre-training-based methods have enhanced point cloud model performance, they have not fundamentally resolved the challenge of local structure representation in point clouds. The limited representational capacity of pure point cloud models continues to constrain the potential of cross-…

UPS: Unified Projection Sharing for Lightweight Single-Image Super-resolution and Beyond

NeurIPS 2024poster

To date, transformer-based frameworks have demonstrated impressive results in single-image super-resolution (SISR). However, under practical lightweight scenarios, the complex interaction of deep image feature extraction and similarity modeling limits the performance of these methods, since they req…

Unveiling Advanced Frequency Disentanglement Paradigm for Low-Light Image Enhancement

ECCV 2024poster

"Previous low-light image enhancement (LLIE) approaches, while employing frequency decomposition techniques to address the intertwined challenges of low frequency (e.g., illumination recovery) and high frequency (e.g., noise reduction), primarily focused on the development of dedicated and complex n…

Locally Varying Distance Transform for Unsupervised Visual Anomaly Detection

ECCV 2022poster

"Unsupervised anomaly detection on image data is notoriously unstable. We believe this is because many classical anomaly detectors implicitly assume data is low dimensional. However, image data is always high dimensional. Images can be projected to a low dimensional embedding but such projections re…
