BiPA: Bilevel Prompt Adaptation for Underwater Instance Segmentation

CVPR 2026

Underwater instance segmentation is essential for fine-grained scene understanding. However, underwater imagery exhibits a strong domain gap from in-air vision due to severe degradation (e.g., turbidity). Consequently, despite its general segmentation ability, SAM degrades sharply underwater. In thi

Learning 3D Occupancy from Beam Overlap in 2D Rotating mmWave Radar

AAAI 2026technical

Robust 3D perception under adverse weather is critical for autonomous systems. While mmWave Radars are inherently weather-resistant, conventional 2D rotating Radar sensors lack direct elevation resolution, limiting their 3D perception ability. Although 4D imaging radars can provide elevation informa

CoA: Towards Real Image Dehazing via Compression-and-Adaptation

CVPR 2025poster

Learning-based image dehazing algorithms have shown remarkable success in synthetic domains. However, real image dehazing is still in suspense due to computational resource constraints and the diversity of real-world scenes. Therefore, there is an urgent need for an algorithm that excels in both eff…

FairGP: A Scalable and Fair Graph Transformer Using Graph Partitioning

AAAI 2025technical

Recent studies have highlighted significant fairness issues in Graph Transformer (GT) models, particularly against subgroups defined by sensitive features. Additionally, GTs are computationally intensive and memory-demanding, limiting their application to large-scale graphs. Our experiments demonstr…

Rethinking Reconstruction and Denoising in the Dark: New Perspective, General Architecture and Beyond

CVPR 2025poster

Recently, enhancing image quality in the original RAW domain has garnered significant attention, with denoising and reconstruction emerging as fundamental tasks. Although some works attempt to couple these tasks, they primarily focus on cascade learning while neglecting task associativity within a b…
