Disco: Densely-overlapping Cell Instance Segmentation via Adjacency-aware Collaborative Coloring

ICLR 2026poster

Accurate cell instance segmentation is foundational for digital pathology analysis. Existing methods based on contour detection and distance mapping still face significant challenges in processing complex and dense cellular regions. Graph coloring-based methods provide a new paradigm for this task,…

Modality Alignment across Trees on Heterogeneous Hyperbolic Manifolds

ICLR 2026poster

Modality alignment is critical for vision-language models (VLMs) to effectively integrate information across modalities. However, existing methods extract hierarchical features from text while representing each image with a single feature, leading to asymmetric and suboptimal alignment. To address t…

Enhancing Chinese Offensive Language Detection with Homophonic Perturbation

EMNLP 2025

Detecting offensive language in Chinese is challenging due to homophonic substitutions used to evade detection. We propose a framework to improve large language models’ robustness against such phonetic attacks. First, we construct HED-COLD, the first large-scale and systematic homophonic dataset for

EffLoc: Lightweight Vision Transformer for Efficient 6-DOF Camera Relocalization

ICRA 2024poster

Camera relocalization is pivotal in computer vision, with applications in AR, drones, robotics, and autonomous driving. It estimates 3D camera position and orientation (6-DoF) from images. Unlike traditional methods like SLAM, recent strides use deep learning for direct end-to-end pose estimation. W…
