CodePercept: Code-Grounded Visual STEM Perception for MLLMs

CVPR 2026

When MLLMs fail at Science, Technology, Engineering, and Mathematics (STEM) visual reasoning, a fundamental question arises: is it due to perceptual deficiencies or reasoning limitations? Through systematic scaling analysis that independently scales perception and reasoning components, we uncover a

Cross-PCR: A Robust Cross-Source Point Cloud Registration Framework

AAAI 2025technical

Due to the density inconsistency and distribution difference between cross-source point clouds, previous methods fail in cross-source point cloud registration. We propose a density-robust feature extraction and matching scheme to achieve robust and accurate cross-source registration. To address the…

Marten: Visual Question Answering with Mask Generation for Multi-modal Document Understanding

CVPR 2025poster

Multi-modal Large Language Models (MLLMs) have introduced a novel dimension to document understanding, i.e., they endow large language models with visual comprehension capabilities; however, how to design a suitable image-text pre-training task for bridging the visual and language modality in docume…

SGOR: Outlier Removal by Leveraging Semantic and Geometric Information for Robust Point Cloud Registration

IROS 2024poster

In this paper, we introduce a new outlier removal method that fully leverages geometric and semantic information, to achieve robust registration. Current semantic-based registration methods only use semantics for point-to-point or instance semantic correspondence generation, which has two problems.…
