3D Aware Region Prompted Vision Language Model

ICLR 2026poster

We present Spatial Region 3D (SR-3D) aware vision-language model that connects single-view 2D images and multi-view 3D data through a shared visual token space. SR-3D supports flexible region prompting, allowing users to annotate regions with bounding boxes, segmentation masks on any frame, or direc…

4D-RGPT: Toward Region-level 4D Understanding via Perceptual Distillation

CVPR 2026

Despite advances in Multimodal LLMs (MLLMs), their ability to reason over 3D structures and temporal dynamics remains limited, constrained by weak 4D perception and temporal understanding. Existing 3D and 4D Video Question Answering (VQA) benchmarks also emphasize static scenes and lack region-level

Eagle: Exploring The Design Space for Multimodal LLMs with Mixture of Encoders

ICLR 2025spotlight

The ability to accurately interpret complex visual information is a crucial topic of multimodal large language models (MLLMs). Recent work indicates that enhanced visual perception significantly reduces hallucinations and improves performance on resolution-sensitive tasks, such as optical character…

Omni-RGPT: Unifying Image and Video Region-level Understanding via Token Marks

CVPR 2025poster

We present Omni-RGPT, a multimodal large language model designed to facilitate region-level comprehension for both images and videos. To achieve consistent region representation across spatio-temporal dimensions, we introduce Token Mark, a set of tokens highlighting the target regions within the vis…

LITA: Language Instructed Temporal-Localization Assistant

ECCV 2024poster

"There has been tremendous progress in multimodal Large Language Models (LLMs). Recent works have extended these models to video input with promising instruction following capabilities. However, an important missing piece is temporal localization. These models cannot accurately answer the “When?” qu…

DiscoBox: Weakly Supervised Instance Segmentation and Semantic Correspondence From Box Supervision

ICCV 2021poster

We introduce DiscoBox, a novel framework that jointly learns instance segmentation and semantic correspondence using bounding box supervision. Specifically, we propose a self-ensembling framework where instance segmentation and semantic correspondence are jointly guided by a structured teacher in ad…
